The Burning Bush
3 Now Moses was pasturing the flock of Jethro his father-in-law, the priest of Midian; and he led the flock to the [a]west side of the wilderness and came to Horeb, the mountain of God. 2 The angel of the Lord appeared to him in a blazing fire from the midst of [b]a bush; and he looked, and behold, the bush was burning with fire, yet the bush was not consumed. 3 So Moses said, “[c]I must turn aside now and see this [d]marvelous sight, why the bush is not burned up.” 4 When the Lord saw that he turned aside to look, God called to him from the midst of the bush and said, “Moses, Moses!” And he said, “Here I am.” 5 Then He said, “Do not come near here; remove your sandals from your feet, for the place on which you are standing is holy ground.”

11 But Moses said to God, “Who am I, that I should go to Pharaoh, and that I should bring the sons of Israel out of Egypt?” 12 And He said, “Certainly I will be with you, and this shall be the sign to you that it is I who have sent you: when you have brought the people out of Egypt, you shall [a]worship God at this mountain.”
13 Then Moses said to God, “Behold, I am going to the sons of Israel, and I will say to them, ‘The God of your fathers has sent me to you.’ Now they may say to me, ‘What is His name?’ What shall I say to them?” 14 God said to Moses, “[b]I AM WHO [c]I AM”; and He said, “Thus you shall say to the sons of Israel, ‘[d]I AM has sent me to you.’” 15 God, furthermore, said to Moses, “Thus you shall say to the sons of Israel, ‘The Lord, the God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob, has sent me to you.’ This is My name forever, and this is My memorial-name [e]to all generations.
