Laws Concerning Warfare

When thou goest out to battle against thine enemies, and seest horses, and chariots, and a people more than thou, be not afraid of them: for the LORD thy God is with thee, which brought thee up out of the land of Egypt.

View commentary
When thou goest out to battle against thine enemies, and seest horses, and chariots, and a people more than thou, be not afraid of them: for the LORD thy God is with thee, which brought thee up out of the land of Egypt.

Military inferiority ('horses, and chariots, and a people more than thou') should not create fear because 'the LORD thy God is with thee.' Divine presence matters more than military advantage. The reminder of exodus ('brought thee up out of Egypt') grounds confidence in past deliverance. God who conquered Egypt's superpower can defeat any enemy. The Hebrew yare (יָרֵא, fear/afraid) is forbidden because covenant relationship guarantees divine aid. This transforms warfare from human contest to divine action. Success depends not on military strength but covenant faithfulness and divine promise.

And it shall be, when ye are come nigh unto the battle, that the priest shall approach and speak unto the people,

View commentary
And it shall be, when ye are come nigh unto the battle, that the priest shall approach and speak unto the people (וְהָיָה כְּקָרׇבְכֶם אֶל־הַמִּלְחָמָה וְנִגַּשׁ הַכֹּהֵן וְדִבֶּר אֶל־הָעָם, ve-hayah ke-qorvekhem el-ha-milchamah ve-nigash ha-kohen ve-dibber el-ha'am)—the kohen (כֹּהֵן, priest) had both religious and military functions in holy war. Unlike surrounding nations where military chaplains offered sacrifices to appease war gods, Israel's priest proclaimed theological truth: Yahweh fights for Israel (v. 4).

The timing is significant: when ye are come nigh unto the battle suggests the priest spoke just before engagement, when fear would be strongest. This wasn't generic religious ceremony but specific pastoral care for soldiers facing death. The priest's role distinguished Israelite warfare as covenant conflict—not merely political expansion but executing divine judgment on Canaanite wickedness (Deuteronomy 9:4-5) and defending the holy nation.

And shall say unto them, Hear, O Israel, ye approach this day unto battle against your enemies: let not your hearts faint, fear not, and do not tremble, neither be ye terrified because of them; faint: Heb. be tender tremble: Heb. make haste

View commentary
The priest addresses troops before battle: 'Hear, O Israel, ye approach this day unto battle against your enemies: let not your hearts faint, fear not, and do not tremble, neither be ye terrified because of them.' Four commands address fear's manifestations: hearts fainting (internal discouragement), fear (anxiety), trembling (physical response), and terror (panic). The repetition emphasizes the reality and danger of fear in battle. The priest's role shows that warfare is spiritual before physical—Israel fights as God's covenant people, requiring spiritual preparation and divine presence.

For the LORD your God is he that goeth with you, to fight for you against your enemies, to save you.

View commentary
Divine warfare: 'For the LORD your God is he that goeth with you, to fight for you against your enemies, to save you.' God doesn't merely observe or bless battles; He actively fights 'for you.' The Hebrew lacham (לָחַם, fight) indicates direct combat. The purpose: 'to save you' (לְהוֹשִׁיעַ, lehoshi'a, deliver/give victory). This transforms warfare from human achievement to divine gift. Israelite soldiers participate, but God secures victory. This prevents boasting ('my hand hath saved me,' Judges 7:2) and maintains dependence. When Israel trusted God, they conquered; when trusting themselves, they failed (Ai after Achan's sin, Joshua 7). Spiritual warfare operates identically—'not by might, nor by power, but by my spirit, saith the LORD' (Zechariah 4:6).

And the officers shall speak unto the people, saying, What man is there that hath built a new house, and hath not dedicated it? let him go and return to his house, lest he die in the battle, and another man dedicate it.

View commentary
What man is there that hath built a new house, and hath not dedicated it? (מִי־הָאִישׁ אֲשֶׁר בָּנָה בַיִת־חָדָשׁ וְלֹא חֲנָכוֹ, mi-ha-ish asher banah bayit-chadash ve-lo chanakho)—the verb chanak (חָנַךְ) means to dedicate, inaugurate, initiate into use. This wasn't merely pragmatic exemption but theological: a man should enjoy the firstfruits of his labor before risking death. The same root gives us Hanukkah, the Feast of Dedication.

Let him go and return to his house, lest he die in the battle, and another man dedicate it—this compassionate exemption reveals God's care for human flourishing, not just military victory. The tragedy isn't merely death but dying before experiencing the fruit of one's work. This reflects Deuteronomy's this-worldly blessings theology: obedience brings tangible rewards in the present life—enjoying your house, vineyard, wife (vv. 5-7). Later biblical texts echo this value: Ecclesiastes 9:9 urges enjoying life's good gifts; Jesus's parable contrasts the rich fool who built bigger barns but died before enjoying them (Luke 12:16-21).

And what man is he that hath planted a vineyard, and hath not yet eaten of it? let him also go and return unto his house, lest he die in the battle, and another man eat of it. eaten: Heb. made it common

View commentary
And what man is he that hath planted a vineyard, and hath not yet eaten of it? (מִי־הָאִישׁ אֲשֶׁר־נָטַע כֶּרֶם)—The third warfare exemption addresses nata (planted) a vineyard but not yet enjoyed its fruit. Under Leviticus 19:23-25, fruit was forbidden for three years, dedicated to God in year four, and available to the owner in year five. To die before enjoying God's blessing on one's labor would be tragic.

This exemption reveals God's compassion for human joy and completion. Holy war required wholehearted focus—a soldier preoccupied with unfinished business would fight halfheartedly. The principle: God wants fully committed warriors, not distracted conscripts forced into service while longing for home.

And what man is there that hath betrothed a wife, and hath not taken her? let him go and return unto his house, lest he die in the battle, and another man take her.

View commentary
And what man is there that hath betrothed a wife, and hath not taken her? (מִי־הָאִישׁ אֲשֶׁר־אֵרַשׂ אִשָּׁה)—The fourth exemption involves aras (betrothed)—legally bound but not yet consummated in marriage. The betrothal period could last a year, during which the couple were legally married but living separately. To die in battle before the wedding night would leave the woman in legal limbo and deny the man his anticipated joy.

This law appears verbatim in the curse of Deuteronomy 28:30: "Thou shalt betroth a wife, and another man shall lie with her." What God graciously exempts in chapter 20, He threatens as covenant curse in chapter 28—underscoring that these aren't arbitrary rules but expressions of God's desire for His people's flourishing.

And the officers shall speak further unto the people, and they shall say, What man is there that is fearful and fainthearted ? let him go and return unto his house, lest his brethren's heart faint as well as his heart. faint: Heb. melt

View commentary
Fearful warriors dismissed: 'And the officers shall speak further unto the people, and they shall say, What man is there that is fearful and fainthearted? let him go and return unto his house, lest his brethren's heart faint as well as his heart.' Fear is contagious—one fearful soldier demoralizes others. The Hebrew yare verak levav (יָרֵא וְרַךְ לֵבָב, 'fearful and soft-hearted') describes paralyzing dread. Such men must leave 'lest his brethren's heart faint'—fear spreads. Gideon's army illustrates this: 32,000 reduced to 10,000 after fearful dismissed (Judges 7:3). Quality matters more than quantity; faithful few triumph over fearful many. This applies spiritually—halfhearted, doubting believers hinder corporate faith more than help it.

And it shall be, when the officers have made an end of speaking unto the people, that they shall make captains of the armies to lead the people. to lead: Heb. to be in the head of the people

View commentary
And it shall be, when the officers have made an end of speaking unto the people, that they shall make captains of the armies to lead the people—After dismissing the fearful and distracted (vv. 5-8), leaders appoint sarei tseva'ot (שָׂרֵי צְבָאוֹת, 'army commanders'). This sequence prioritizes quality over quantity: a small, committed force exceeds a large, anxious mob. Gideon exemplified this—God reduced 32,000 to 300 (Judges 7:2-7), proving the battle is the LORD's (1 Samuel 17:47).

Spiritual warfare operates identically: The weapons of our warfare are not carnal (2 Corinthians 10:4). God seeks wholehearted warriors, not halfhearted crowds. Paul commands Timothy: Endure hardness, as a good soldier of Jesus Christ. No man that warreth entangleth himself with the affairs of this life (2 Timothy 2:3-4). The dismissed soldiers weren't cowards but distracted—equally disqualified. Effective spiritual warfare requires focused devotion.

When thou comest nigh unto a city to fight against it, then proclaim peace unto it.

View commentary
When thou comest nigh unto a city to fight against it, then proclaim peace unto it—Even in warfare, Israel must offer shalom (שָׁלוֹם, peace, wholeness) first. This requirement distinguished Israel from aggressive conquerors—they fought defensively or under divine mandate, not for imperial expansion. Proclaim (קָרָא, qara, 'call out, summon') suggests public, formal offer—opportunity for negotiation, not deceptive ambush.

Jesus commanded: Love your enemies, bless them that curse you, do good to them that hate you (Matthew 5:44). Paul echoes: If it be possible, as much as lieth in you, live peaceably with all men (Romans 12:18). Yet Jesus also declared: I came not to send peace, but a sword (Matthew 10:34)—the gospel divides (Luke 12:51-53). We offer peace (the gospel), but if rejected, judgment follows. God's warfare ethic: seek peace first, fight only when necessary.

And it shall be, if it make thee answer of peace, and open unto thee, then it shall be, that all the people that is found therein shall be tributaries unto thee, and they shall serve thee.

View commentary
And it shall be, if it make thee answer of peace, and open unto thee, then it shall be, that all the people that is found therein shall be tributaries unto thee, and they shall serve thee—Cities accepting peace become mas (מַס, 'forced labor, tribute')—subordinate but not exterminated. This merciful alternative to total war allowed survival in exchange for service. Gibeon secured such a treaty through deception (Joshua 9:3-27), becoming woodcutters and water-carriers.

This foreshadows gospel dynamics: rebels against the King may surrender and live, entering service rather than destruction. The wages of sin is death; but the gift of God is eternal life (Romans 6:23). Yet surrender means slavery's exchange: Being then made free from sin, ye became the servants of righteousness (Romans 6:18). We escape death-sentence by becoming Christ's bondservants—whose service is perfect freedom (Book of Common Prayer). Tribute depicts redeemed humanity serving the King who conquered us.

And if it will make no peace with thee, but will make war against thee, then thou shalt besiege it:

View commentary
And if it will make no peace with thee, but will make war against thee, then thou shalt besiege it—Rejection of peace justifies siege. The Hebrew tsur (צוּר, 'bind, besiege, confine') pictures surrounding the city, cutting off supplies until starvation forces surrender. This was protracted, costly warfare—final resort after peace offered and refused.

God Himself practices this principle: I have no pleasure in the death of the wicked; but that the wicked turn from his way and live (Ezekiel 33:11). Yet persistent rebellion necessitates judgment. Revelation depicts Christ's final siege: Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him (Revelation 3:20)—but those refusing entry face ultimate siege: The wicked shall be turned into hell (Psalm 9:17). God's patience exhausts only after extended opportunity.

And when the LORD thy God hath delivered it into thine hands, thou shalt smite every male thereof with the edge of the sword:

View commentary
And when the LORD thy God hath delivered it into thine hands, thou shalt smite every male thereof with the edge of the sword—Victory belongs to the LORD—human effort doesn't produce conquest; divine intervention does. The herem (חֵרֶם, 'devotion to destruction') applied to Canaanite cities involved executing combatants (every male, זָכָר, zakhar), removing military threat and judgment on persistent idolatry.

Modern readers recoil at divine violence, yet God's holiness demands judgment. The soul that sinneth, it shall die (Ezekiel 18:20). Canaan's destruction foreshadows hell's reality: The Lord Jesus shall be revealed from heaven with his mighty angels, in flaming fire taking vengeance on them that know not God (2 Thessalonians 1:7-8). Israel's warfare enacted God's judicial prerogative. We can't command such wars (lacking divine authority), but we acknowledge God's right to judge.

But the women, and the little ones, and the cattle, and all that is in the city, even all the spoil thereof, shalt thou take unto thyself; and thou shalt eat the spoil of thine enemies, which the LORD thy God hath given thee. take: Heb. spoil

View commentary
But the women, and the little ones, and the cattle, and all that is in the city, even all the spoil thereof, shalt thou take unto thyself—Non-combatants (women and little ones) and possessions become shalal (שָׁלָל, 'plunder, spoil'). This contrasts with Canaanite herem (total destruction, Joshua 6:17-19) where even spoil was forbidden. For distant nations (non-Canaanite), Israel could benefit economically from conquest.

This provision prevented wasteful destruction while removing military capacity. New Testament parallel: spiritual warfare targets demonic powers (we wrestle not against flesh and blood, but against principalities, against powers, Ephesians 6:12), not people. We 'destroy' false ideologies (casting down imaginations, and every high thing that exalteth itself against the knowledge of God, 2 Corinthians 10:5) while 'plundering' useful elements (Paul quoted pagan poets, Acts 17:28, Titus 1:12).

Thus shalt thou do unto all the cities which are very far off from thee, which are not of the cities of these nations.

View commentary
Thus shalt thou do unto all the cities which are very far off from thee, which are not of the cities of these nations—This verse distinguishes warfare categories: very far off (distant, non-Canaanite) versus these nations (the seven Canaanite peoples, Deuteronomy 7:1). Distant cities receive peace offers and mercy if they surrender; Canaanite cities face total herem (next verses) because their proximity threatens Israel's covenant fidelity through idolatrous influence.

Proximity determines danger—not ethnicity but spiritual contagion risk. Paul warns: Evil communications corrupt good manners (1 Corinthians 15:33). The principle applies spiritually: Come out from among them, and be ye separate (2 Corinthians 6:17). We engage distant culture (missions, evangelism) but guard against intimate spiritual compromise (close fellowship with unbelief). Jesus ate with sinners (evangelism) but didn't adopt their practices (sanctification).

But of the cities of these people, which the LORD thy God doth give thee for an inheritance, thou shalt save alive nothing that breatheth:

View commentary
But of the cities of these people, which the LORD thy God doth give thee for an inheritance, thou shalt save alive nothing that breatheth—The Canaanite herem demanded total destruction: nothing that breatheth (כָּל־נְשָׁמָה, kol-neshamah, literally 'every breath'). This wasn't ethnic cleansing but spiritual surgery—removing cancer threatening Israel's covenant relationship. God's explicit command (next verse) makes His purpose clear: prevent idolatry contagion.

Israel's incomplete obedience (failing to execute full herem) caused centuries of apostasy. They did not destroy the nations, concerning whom the LORD commanded them: But were mingled among the heathen, and learned their works...Therefore was the wrath of the LORD kindled against his people (Psalm 106:34-35, 40). Spiritual compromise never stays contained; it metastasizes. Jesus demands similar ruthlessness with personal sin: If thy right eye offend thee, pluck it out (Matthew 5:29)—radical amputation prevents spiritual death.

But thou shalt utterly destroy them; namely, the Hittites, and the Amorites, the Canaanites, and the Perizzites, the Hivites, and the Jebusites; as the LORD thy God hath commanded thee:

View commentary
But thou shalt utterly destroy them; namely, the Hittites, and the Amorites, the Canaanites, and the Perizzites, the Hivites, and the Jebusites; as the LORD thy God hath commanded thee—The seven nations listed represent complete Canaanite civilization. Utterly destroy (הַחֲרֵם תַּחֲרִימֵם, hacharem tacharimem, intensive doubling: 'you shall certainly devote to destruction') emphasizes non-negotiable obedience. The phrase as the LORD thy God hath commanded anchors this in divine authority, not human cruelty.

This isn't genocide (ethnic elimination) but theocide (false-god elimination). Rahab and the Gibeonites survived by embracing YHWH (Joshua 2, 9)—proving ethnicity wasn't the issue, idolatry was. Similarly, God demands spiritual herem: Mortify therefore your members which are upon the earth; fornication, uncleanness, inordinate affection, evil concupiscence, and covetousness, which is idolatry (Colossians 3:5). No quarter given to indwelling sin.

That they teach you not to do after all their abominations, which they have done unto their gods; so should ye sin against the LORD your God.

View commentary
That they teach you not to do after all their abominations, which they have done unto their gods; so should ye sin against the LORD your God—The reason for herem: preventing idolatrous abominations (תּוֹעֵבוֹת, to'evot, 'detestable practices') from infecting Israel. Canaanite worship included child sacrifice (they burnt their sons and their daughters in the fire to their gods, Deuteronomy 12:31), cultic prostitution, and divination. Exposure meant adoption: they teach you (לְמַדְתֶּם, lemadtem, instructing, training).

The warning proved prophetic. Israel learned Canaanite practices: They sacrificed their sons and their daughters unto devils, and shed innocent blood (Psalm 106:37-38). God's preventative judgment (destroy them first) became necessary corrective judgment (exile, 586 BC). The principle stands: Evil company corrupts good habits (1 Corinthians 15:33, NKJV). Tolerating sin's presence guarantees sin's dominance. Paul commands: Abstain from all appearance of evil (1 Thessalonians 5:22).

When thou shalt besiege a city a long time, in making war against it to take it, thou shalt not destroy the trees thereof by forcing an axe against them: for thou mayest eat of them, and thou shalt not cut them down (for the tree of the field is man's life ) to employ them in the siege : for the: or, for, O man, the tree of the field is to be employed in the siege to employ: Heb. to go from before thee

View commentary
When thou shalt besiege a city a long time, in making war against it to take it, thou shalt not destroy the trees thereof by forcing an axe against them—Even in warfare, God requires environmental stewardship. Fruit trees provide food (מַאֲכָל, ma'akal) and shouldn't be destroyed militarily. The prohibition against forcing an axe (נִדַּחְתָּ עֲלֵיהֶם גַּרְזֶן, nidachta alehem garzen, 'wielding an axe against them') forbids scorched-earth tactics unnecessarily harming creation.

This reveals God's comprehensive covenant: redemption includes creation care. Paul declares: The earnest expectation of the creature waiteth for the manifestation of the sons of God (Romans 8:19)—creation groans for humanity's restoration. Jesus multiplied food (feeding thousands) rather than waste it. The tree law taught Israel: dominion (Genesis 1:28) means stewardship, not exploitation. Even urgent military needs don't justify needless destruction.

Only the trees which thou knowest that they be not trees for meat, thou shalt destroy and cut them down; and thou shalt build bulwarks against the city that maketh war with thee, until it be subdued. it: Heb. it come down

View commentary
Only the trees which thou knowest that they be not trees for meat, thou shalt destroy and cut them down; and thou shalt build bulwarks against the city that maketh war with thee, until it be subdued—Non-fruit trees may be cut for siege equipment (bulwarks, מָצוֹר, matsor, 'siege works, fortifications'). This balances stewardship with military necessity: preserve productive resources; utilize non-productive ones. The phrase which thou knowest requires discernment—soldiers must actively identify and protect fruit trees.

Spiritual application: distinguish what nourishes from what's expendable. Lay aside every weight, and the sin which doth so easily beset us (Hebrews 12:1)—cut away encumbrances (weights) and sins, but preserve what feeds spiritual growth. Not everything culturally neutral is spiritually nutritious. Paul declares: All things are lawful for me, but all things are not expedient: all things are lawful for me, but all things edify not (1 Corinthians 10:23). Wisdom discerns what to cut and what to cultivate.
