Genesis 19:1, 29

Now the two angels came to Sodom in the evening as Lot was sitting in the gate of Sodom. When Lot saw them, he rose to meet them and bowed down with his face to the ground.

Thus it came about, when God destroyed the cities of the valley, that God remembered Abraham, and sent Lot out of the midst of the overthrow, when He overthrew the cities in which Lot lived.
