Exodus 3:2-6 King James Version (KJV)
2 And the angel of the Lord appeared unto him in a flame of fire out of the midst of a bush: and he looked, and, behold, the bush burned with fire, and the bush was not consumed.
3 And Moses said, I will now turn aside, and see this great sight, why the bush is not burnt.
4 And when the Lord saw that he turned aside to see, God called unto him out of the midst of the bush, and said, Moses, Moses. And he said, Here am I.
5 And he said, Draw not nigh hither: put off thy shoes from off thy feet, for the place whereon thou standest is holy ground.
6 Moreover he said, I am the God of thy father, the God of Abraham, the God of Isaac, and the God of Jacob. And Moses hid his face; for he was afraid to look upon God.
Exodus 3:2-6 New International Version (NIV)
2 There the angel of the Lord appeared to him in flames of fire from within a bush. Moses saw that though the bush was on fire it did not burn up. 3 So Moses thought, “I will go over and see this strange sight—why the bush does not burn up.”
4 When the Lord saw that he had gone over to look, God called to him from within the bush, “Moses! Moses!”
And Moses said, “Here I am.”
5 “Do not come any closer,” God said. “Take off your sandals, for the place where you are standing is holy ground.” 6 Then he said, “I am the God of your father,[a] the God of Abraham, the God of Isaac and the God of Jacob.” At this, Moses hid his face, because he was afraid to look at God.
