Exodus 3:16-18

16“Go, assemble the elders of Israel and say to them, ‘The Lord, the God of your fathers—the God of Abraham, Isaac and Jacob—appeared to me and said: I have watched over you and have seen what has been done to you in Egypt.

17And I have promised to bring you up out of your misery in Egypt into the land of the Canaanites, Hittites, Amorites, Perizzites, Hivites and Jebusites—a land flowing with milk and honey.’

18“The elders of Israel will listen to you. Then you and the elders are to go to the king of Egypt and say to him, ‘The Lord, the God of the Hebrews, has met with us. Let us take a three-day journey into the wilderness to offer sacrifices to the Lord our God.’
