Exodus 3:5

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.

7 And the LORD said, I have surely seen the affliction of my people which [are] in Egypt, and have heard their cry by reason of their taskmasters; for I know their sorrows;

8 And I am come down to deliver them out of the hand of the Egyptians, and to bring them up out of that land unto a good land and a large, unto a land flowing with milk and honey; unto the place of the Canaanites, and the Hittites, and the Amorites, and the Perizzites, and the Hivites, and the Jebusites.
