“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. 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. And Moses said, I will now turn aside, and see this great sight, why the bush is not burnt. 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.” —Exodus 3:1–6,
