Exodus 3:18-20

Revised Standard Version

¹⁸ And they will hearken to your voice; and you and the elders of Israel shall go to the king of Egypt and say to him, ‘The Lord, the God of the Hebrews, has met with us; and now, we pray you, let us go a three days’ journey into the wilderness, that we may sacrifice to the Lord our God.’ ¹⁹ I know that the king of Egypt will not let you go unless compelled by a mighty hand.^{[a] 20} So I will stretch out my hand and smite Egypt with all the wonders which I will do in it; after that he will let you go.
