Exodus 3:1-6 KJV

1 Now Moses kept * the flock of Jethro his father in law , the priest of Midian: and he led the flock to the backside of the desert, and came to the mountain of God, even to Horeb.
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.
