Genesis 18:5

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

And he said, “Come in, blessed of Yahweh! Why do you stand outside since I have prepared the house and a place for the camels?”

Now it happened on the fourth day that they got up early in the morning, and he arose to go; and the girl’s father said to his son-in-law, “Sustain yourself with a piece of bread, and afterward you may go.”

And wine which makes man’s heart glad, To make his face glisten more than oil, And food which sustains man’s heart.

Do not neglect to show hospitality to strangers, for by this some have entertained angels without knowing it.
