Exodus 3:19-22

19But I know that the king of Egypt will not let you go, no, not by a powerful hand. 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 eyes of the Egyptians, and it shall come to pass, when ye go out, that ye shall not go out empty; 22but every woman shall ask of her neighbour, and of her that is the inmate of her house, utensils of silver, and utensils of gold, and clothing; and ye shall put [them] on your sons and on your daughters, and shall spoil the Egyptians.
