Genesis 18:1-5

Then ADONAI appeared to him at Mamre’s large trees while he was sitting in the entrance of his tent during the heat of the day. When he lifted up his eyes to see, suddenly, three men were standing right by him. When he saw them, he ran from the entrance of his tent to meet them and bowed down to the ground. Then he said, “My Lord, if now I have found favor in your eyes, please do not pass by your servant. Please let a little water be brought so you can wash your feet, and make yourselves comfortable under the tree. And let me bring a bit of bread so that you can refresh yourselves—then you can pass on—since you have passed by your servant. They said, “Do just as you have said.”
