Exodus 3:18-22

18And 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, Yhwh God of the Hebrews hath met with us: and now let us go, we beseech thee, three days’ journey into the wilderness, that we may sacrifice to Yhwh our God.

19And I am sure that the king of Egypt will not let you go, no, not by a mighty hand.1 20And I will stretch out 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. 21And I will give this people favour in the sight of the Egyptians: and it shall come to pass, that, when ye go, ye shall not go empty: 22But every woman shall ask of her neighbour, 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 spoil the Egyptians.2
