Genesis 18:1-5

YAHWEH appeared once again to Abraham while he lived by the oak grove of Mamre. During the hottest part of the day, as Abraham sat at his tent door, he looked up and suddenly saw three men standing nearby. As soon as he saw them, he ran from his tent to welcome them. He bowed down to the ground and said, “My Lord, if I have found favor in your sight, don’t pass me by. Stay for a while with your servant. I’ll have some water brought to you all so that you can wash your feet. Rest here a while under the tree. Since you’ve stopped by your servant’s home and honored me with your presence, I’ll have food prepared for you so that you can be refreshed; then you can go on your way.” “Very well,” they responded, “go ahead and do as you have said.”
