Exodus 3:16-18

16Go and gather the elders of Israel together, and say unto them, Jehovah the 1God of your fathers, the 2God of Abraham, Isaac, and Jacob, hath appeared to me, saying, I have indeed visited you, and [seen] that which is done unto you in Egypt;

17and I have said, I will bring you up out of the affliction of Egypt, unto the land of the Canaanites, and the Hittites, and the Amorites, and the Perizzites, and the Hivites, and the Jebusites, unto a land flowing with milk and honey.

18And they shall hearken to thy voice. And thou shalt come, thou and the elders of Israel, unto the king of Egypt, and ye shall say unto him, Jehovah, the 3God of the Hebrews, hath met with us; and now, let us go, we pray thee, three days' journey into the wilderness, that we may sacrifice to Jehovah our 4God.
