18 And they shall hearken to thy voice: and thou shalt come, thou and the elders of Israel, unto the king of Egypt, and ye shall say unto him, Jehovah, the God of the Hebrews, hath met with us: and now let us go, we pray thee, three days' journey into the wilderness, that we may sacrifice to Jehovah our God. 19 And I know that the king of Egypt will not give you leave to go, no, not by a mighty hand. 20 And I will put forth my hand, and smite Egypt with all my wonders which I will do in the midst thereof: and after that he will let you go. 21 And I will give this people favor in the sight of the Egyptians: and it shall come to pass, that, when ye go, ye shall not go empty. 22 But every woman shall ask of her neighbor, and of her that sojourneth in her house, jewels of silver, and jewels of gold, and raiment: and ye shall put them upon your sons, and upon your daughters; and ye shall despoil the Egyptians.

Commentary on Exodus 3:16-22

(Read Exodus 3:16-22)

Moses' success with the elders of Israel would be good. God, who, by his grace, inclines the heart, and opens the ear, could say beforehand, They shall hearken to thy voice; for he would make them willing in this day of power. As to Pharaoh, Moses is here told that petitions and persuasions, and humble complaints, would not prevail with him; nor a mighty hand stretched out in signs and wonders. But those will certainly be broken by the power of God's hand, who will not bow to the power of his word. Pharaoh's people should furnish Israel with riches at their departure. In Pharaoh's tyranny and Israel's oppression, we see the miserable, abject state of sinners. However galling the yoke, they drudge on till the Lord sends redemption. With the invitations of the gospel, God sends the teaching of his Spirit. Thus are men made willing to seek and to strive for deliverance. Satan loses his power to hold them, they come forth with all they have and are, and apply all to the glory of God and the service of his church.
