Genesis 19:28-30 Revised Standard Version Catholic Edition (RSVCE)
28 and he looked down toward Sodom and Gomor′rah and toward all the land of the valley, and beheld, and lo, smoke of the land went up like the smoke of a furnace.
29 So it was that, when God destroyed the cities of the valley, God remembered Abraham, and sent Lot out of the midst of the overthrow, when he overthrew the cities in which Lot dwelt.
