Genesis 18:6

and said, “My lord, if now I have found favor in your sight, please don’t go away from your servant.

Now let a little water be fetched, wash your feet, and rest yourselves under the tree.

I will get a piece of bread so you can refresh your heart. After that you may go your way, now that you have come to your servant.”

They said, “Very well, do as you have said.”

Abraham ran to the herd, and fetched a tender and good calf, and gave it to the servant. He hurried to dress it.

He took butter, milk, and the calf which he had dressed, and set it before them. He stood by them under the tree, and they ate.

They asked him, “Where is Sarah, your wife?”

He said, “There, in the tent.”
