Genesis 18:3-5

and said, “My Lord, if I have now found favor in Your sight, do not pass on by Your servant. Please let a little water be brought, and wash your feet, and rest yourselves under the tree. And I will bring a morsel of bread, that you may refresh your hearts. After that you may pass by, inasmuch as you have come to your servant.” They said, “Do as you have said.”
