What Does Exodus 4:21 Mean?

“And the LORD said unto Moses, When thou goest to return into Egypt, see that thou do all those wonders before Pharaoh, which I have put in thine hand: but I will harden his heart, that he shall not let the people go.”

Context

And the LORD said unto Moses in Midian, Go, return into Egypt: for all the men are dead which sought thy life.

And Moses took his wife and his sons, and set them upon an ass, and he returned to the land of Egypt: and Moses took the rod of God in his hand.

And the LORD said unto Moses, When thou goest to return into Egypt, see that thou do all those wonders before Pharaoh, which I have put in thine hand: but I will harden his heart, that he shall not let the people go.

And thou shalt say unto Pharaoh, Thus saith the LORD, Israel is my son, even my firstborn:

And I say unto thee, Let my son go, that he may serve me: and if thou refuse to let him go, behold, I will slay thy son, even thy firstborn.

Commentary

Ellicott’s Commentary for English Readers

(21) **All those wonders.**—Not the “three signs” of Exodus 3:3-9, but the “portents” or “wonders “which were to be done before Pharaoh, and which had been alluded to in Exodus 3:20. These were, in the counsel of God, already “put into Moses’ hand,” though their exact nature was as yet unknown to Moses himself. **I will harden his heart.**—The hardening of Pharaoh’s heart has been the subject of much controversy. It is ascribed to God in this place, and again in Exodus 7:3; Exodus 9:12; Exodus 10:1; Exodus 10:20; Exodus 10:27; Exodus 14:4; Exodus 14:8; to Pharaoh in Exodus 8:15; Exodus 8:32; and Exodus 9:34; to the action of the heart itself in Exodus 7:13; Exodus 7:22; Exodus 9:7; Exodus 9:35. It is conceivable that these may be simply three forms of speech, and that the actual operation was one and the same in every case. Or, three different modes of operation may be meant. It is in favour of the latter view, that each term has a period during which it is predominant. In the narrative of what happened, the action of the heart is itself predominant in the first period; that of Pharaoh on his heart in the second; that of God in the third. We may suppose that, at first, Pharaoh’s nature was simply not impressed, and that then his heart is said to have “hardened itself,” or “remained hard;” that after a while, he began to be impressed; but by an effort of his will controlled himself, and determined that he would not yield: thus “hardening his own heart;” finally, that after he had done this twice (Exodus 8:15; Exodus 8:32), God stepped in and “smote him with a spirit of blindness and infatuation,” as a judgment upon him (Exodus 9:12), thus, finally, “hardening” him (comp. Romans 9:18). This divine action was repeated, on three subsequent occasions (Exodus 10:20; Exodus 10:27; Exodus 14:8), Pharaoh’s time of probation being past, and God using him as a mere means of showing forth His glory. There is nothing in this contrary to the general teaching of the Scriptures, or to the Divine Perfection.
