Genesis 18:4-8

Please let a little water be brought and wash your feet, and make yourselves comfortable under the tree;

and I will bring a piece of bread, so that you may refresh yourselves; after that you may go on, since you have visited your servant.” And they said, “So do as you have said.”

So Abraham hurried into the tent to Sarah, and said, “Quickly, prepare three measures of fine flour, knead it, and make bread cakes.”

Abraham also ran to the herd, and took a tender and choice calf and gave it to the servant, and he hurried to prepare it.

He took curds and milk and the calf which he had prepared, and set it before them; and he was standing by them under the tree as they ate.
