Exodus 3:1-2

Darby Translation

3 And Moses tended the flock of Jethro his father-in-law, the priest of Midian. And he led the flock behind the wilderness, and came to the mountain of God—to Horeb.

² And the Angel of Jehovah appeared to him in a flame of fire out of the midst of a thorn-bush: and he looked, and behold, the thorn-bush burned with fire, and the thorn-bush was not being consumed.
