Exodus 3:18-22

Then they will pay attention to what you say; and you with the elders of Israel will come to the king of Egypt, and you will say to him, ‘The Lord, the God of the Hebrews, has met with us. So now, please let us go a three days’ journey into the wilderness, so that we may sacrifice to the Lord our God.’

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.”
