Exodus 3:1-2

New Revised Standard Version, Anglicised Catholic Edition

Moses at the Burning Bush

3 Moses was keeping the flock of his father-in-law Jethro, the priest of Midian; he led his flock beyond the wilderness, and came to Horeb, the mountain of God. ² There the angel of the Lord appeared to him in a flame of fire out of a bush; he looked, and the bush was blazing, yet it was not consumed.
