Exodus 3:18-22

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. And I know that the king of Egypt will not give you leave to go, no, not by a mighty hand. 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. 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. 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.
