Exodus 3:13-18

13And Moses said to God, Behold, when I come to the children of Israel, and shall say to them, The God of your fathers hath sent me to you; and they shall say to me, What is his name? what shall I say to them? 14And God said to Moses, I AM THAT I AM: and he said, Thus shalt thou say to the children of Israel, I AM hath sent me to you. 15And God said moreover to Moses, Thus shalt thou say to the children of Israel, The LORD God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob, hath sent me to you: this is my name for ever, and this is my memorial to all generations.

16Go, and gather the elders of Israel together, and say to them, The LORD God of your fathers, the God of Abraham, of Isaac, and of Jacob, appeared to me, saying, I have surely visited you, and seen that which is done to you in Egypt: 17And I have said, I will bring you up out of the affliction of Egypt to the land of the Canaanites, and the Hittites, and the Amorites, and the Perizzites, and the Hivites, and the Jebusites, to a land flowing with milk and honey. 18And they shall hearken to thy voice: and thou shalt come, thou and the elders of Israel, to the king of Egypt, and ye shall say to him, The LORD God of the Hebrews hath met with us: and now let us go, we beseech thee, three days’ journey into the wilderness, that we may sacrifice to the LORD our God.
