Exodus 3:19-23

But I know that the king of Egypt will not permit you to go, except under compulsion.

So I will reach out with My hand and strike Egypt with all My miracles which I shall do in the midst of it; and after that he will let you go.

I will grant this people favor in the sight of the Egyptians; and it shall be that when you go, you will not go empty-handed.

But every woman shall ask her neighbor and the woman who lives in her house for articles of silver and articles of gold, and clothing; and you will put them on your sons and daughters. So you will plunder the Egyptians.”
