Exodus 3:20-22

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.
