Exodus 3:13-21

And Moses said unto God, Behold, when I come unto the children of Israel, and shall say unto them, The God of your fathers hath sent me unto you; and they shall say to me, What is his name? What shall I say unto them? And God said unto Moses, I AM THAT I AM: and he said, Thus shalt thou say unto the children of Israel, I AM hath sent me unto you. And God said moreover unto Moses, Thus shalt thou say unto the children of Israel, Jehovah, the God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob, hath sent me unto you: this is my name for ever, and this is my memorial unto all generations. Go, and gather the elders of Israel together, and say unto them, Jehovah, the God of your fathers, the God of Abraham, of Isaac, and of Jacob, hath appeared unto me, saying, I have surely visited you, and seen that which is done to you in Egypt: and I have said, I will bring you up out of the affliction of Egypt unto the land of the Canaanite, and the Hittite, and the Amorite, and the Perizzite, and the Hivite, and the Jebusite, unto a land flowing with milk and honey. And 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 God 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 God. And I know that the king of Egypt will not give you leave to go, no, not by a mighty hand. And I will put forth my hand, and smite Egypt with all my wonders which I will do in the midst thereof: and after that he will let you go. And I will give this people favor in the sight of the Egyptians: and it shall come to pass, that, when ye go, ye shall not go empty.
