Exodus 3:16-18

16“Go and assemble the elders of Israel and say to them: The Lord, the God of your ancestors, the God of Abraham, Isaac, and Jacob, has appeared to me and said: I have paid close attention to you and to what has been done to you in Egypt.

17And I have promised you that I will bring you up from the misery of Egypt to the land of the Canaanites, Hethites, Amorites, Perizzites, Hivites, and Jebusites — a land flowing with milk and honey.

18They will listen to what you say. Then you, along with the elders of Israel, must go to the king of Egypt and say to him: The Lord, the God of the Hebrews, has met with us. Now please let us go on a three-day trip into the wilderness so that we may sacrifice to the Lord our God.
