Now Moses was keeping the flock of Jethro (Reuel) his father-in-law, the priest of Midian; and he led his flock to the west side of the wilderness and came to Horeb (Sinai), the mountain of God. The Angel of the LORD appeared to him in a blazing flame of fire from the midst of a bush; and he looked, and behold, the bush was on fire, yet it was not consumed. So Moses said, “I must turn away [from the flock] and see this great sight--why the bush is not burned up.” When the LORD saw that he turned away [from the flock] to look, God called to him from the midst of the bush and said, “Moses, Moses!” And he said, “Here I am.” Then God said, “Do not come near; take your sandals off your feet [out of respect], because the place on which you are standing is holy ground.” Then He said, “I am the God of your father, the God of Abraham, the God of Isaac, and the God of Jacob.” Then Moses hid his face, because he was afraid to look at God.
The LORD said, “I have in fact seen the affliction (suffering, desolation) of My people who are in Egypt, and have heard their cry because of their taskmasters (oppressors); for I know their pain and suffering. So I have come down to rescue them from the hand (power) of the Egyptians, and to bring them up from that land to a land [that is] good and spacious, to a land flowing with milk and honey [a land of plenty]--to the place of the Canaanite, the Hittite, the Amorite, the Perizzite, the Hivite, and the Jebusite. Now, behold, the cry of the children of Israel has come to Me; and I have also seen how the Egyptians oppress them.
Therefore, come now, and I will send you to Pharaoh, and then bring My people, the children of Israel, out of Egypt.” But Moses said to God, “Who am I, that I should go to Pharaoh, and that I should bring the children of Israel out of Egypt?” And God 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 serve and worship God at this mountain.”
Then Moses said to God, “Behold, when I come to the Israelites and say to them, ‘The God of your fathers (ancestors) has sent me to you,’ and they say to me, ‘What is His name?’ What shall I say to them?” God said to Moses, “I AM WHO I AM”; and He said, “You shall say this to the Israelites, ‘I AM has sent me to you.’” Then God also said to Moses, “This is what you shall say to the Israelites, ‘The LORD, the God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob (Israel), has sent me to you.’ This is My Name forever, and this is My memorial [name] to all generations.
