Exodus 3:11-20 New American Bible (Revised Edition) (NABRE)
11 But Moses said to God, “Who am I[a] that I should go to Pharaoh and bring the Israelites out of Egypt?” 12 God answered: I will be with you; and this will be your sign[b] that I have sent you. When you have brought the people out of Egypt, you will serve God at this mountain. 13 “But,” said Moses to God, “if I go to the Israelites and say to them, ‘The God of your ancestors has sent me to you,’ and they ask me, ‘What is his name?’ what do I tell them?” 14 God replied to Moses: I am who I am.[c] Then he added: This is what you will tell the Israelites: I AM has sent me to you.
15 God spoke further to Moses: This is what you will say to the Israelites: The Lord, the God of your ancestors, the God of Abraham, the God of Isaac, and the God of Jacob, has sent me to you.
This is my name forever;
16 Go and gather the elders of the Israelites, and tell them, The Lord, the God of your ancestors, the God of Abraham, Isaac, and Jacob, has appeared to me and said: I have observed you and what is being done to you in Egypt; 17 so I have decided to lead you up out of your affliction in Egypt into the land of the Canaanites, the Hittites, the Amorites, the Perizzites, the Girgashites, the Hivites and the Jebusites, a land flowing with milk and honey. 18 They will listen to you. Then you and the elders of Israel will go to the king of Egypt and say to him: The Lord, the God of the Hebrews, has come to meet us. So now, let us go a three days’ journey in the wilderness to offer sacrifice to the Lord, our God. 19 Yet I know that the king of Egypt will not allow you to go unless his hand is forced. 20 So I will stretch out my hand and strike Egypt with all the wondrous deeds I will do in its midst. After that he will let you go.
