Genesis 18:3-5

3and Abraham said, “My lord, if now I have found favor in your sight, please do not pass by your servant [without stopping to visit].

4Please let a little water be brought [by one of my servants] and [you may] wash your feet, and recline and rest comfortably under the tree.

5And I will bring a piece of bread to refresh and sustain you; after that you may go on, since you have come to your servant.” And they replied, “Do as you have said.”
