Genesis 18:3-5

3and said, “My lord, if I have found favor with you, please do not go on past your servant.

4Let a little water be brought, that you may wash your feet and rest yourselves under the tree.

5I will bring a bit of bread so that you may strengthen yourselves. This is why you have passed your servant’s way. Later, you can continue on.” “Yes,” they replied, “do as you have said.”
