Commentary

KJV Study Commentary
"His bones are as strong pieces of brass; his bones are like bars of iron." The comparison to brass (nechushshah, נְחוּשָׁה) and iron (barzel, בַּרְזֶל) emphasizes skeletal strength. Ancient metallurgy produced the hardest materials humans knew—yet Behemoth's bones surpass these. God designs creatures with specifications exceeding human engineering. This teaches that divine creation employs "materials" and principles humans cannot replicate, demonstrating the Creator's superior wisdom and power.

Historical & Cultural Context

Bronze and iron represented the hardest substances in ancient technology, used for weapons and tools. God's comparison taught that even humanity's greatest technological achievements pale before natural design in God's creation. This would humble human pride in technological progress.

Reflection Questions

  2. What human achievements are you tempted to pride yourself in, forgetting they cannot match God's creative work?
