Exodus 3:1-2

DouayRheims(i) 1 Now Moses fed the sheep of Jethro, his father in law, the priest of Madian: and he drove the flock to the inner parts of the desert, and came to the mountain of God, Horeb. 2 And the Lord appeared to him in a flame of fire out of the midst of a bush: and he saw that the bush was on fire, and was not burnt.
