Genesis 18:2-8

2 He looked up and saw three men standing near him. When he saw them, he ran from the tent entrance to meet them, and bowed down to the ground.
3 He said, "My lord, if I find favor with you, do not pass by your servant.
4 Let a little water be brought, and wash your feet, and rest yourselves under the tree.
5 Let me bring a little bread, that you may refresh yourselves, and after that you may pass on—since you have come to your servant." So they said, "Do as you have said."
6 And Abraham hastened into the tent to Sarah, and said, "Make ready quickly three measures of choice flour, knead it, and make cakes."
7 Abraham ran to the herd, and took a calf, tender and good, and gave it to the servant, who hastened to prepare it.
8 Then he took curds and milk and the calf that he had prepared, and set it before them; and he stood by them under the tree while they ate.
