Exodus 3:16-18

16Go, gather the elders (tribal leaders) of Israel together, and say to them, ‘The Lord, the God of your fathers, the God of Abraham, of Isaac, and of Jacob, appeared to me, saying, “I am indeed concerned about you and what has been done to you in Egypt.

17So I said I will bring you up out of the suffering and oppression of Egypt to the land of the Canaanite, the Hittite, the Amorite, the Perizzite, the Hivite, and the Jebusite, to a land flowing with milk and honey.” ’

18The elders [of the tribes] will listen and pay attention to what you say; and you, with the elders of Israel, shall go to the king of Egypt and you shall say to him, ‘The Lord, the God of the Hebrews, has met with us; so now, please, [we ask and plead with you,] let us go on a three days’ journey into the wilderness, so that we may sacrifice to the Lord our God.’
