Genesis 18:2-7

2Abraham looked up and saw three men standing nearby. When he saw them, he hurried from the entrance of his tent to meet them and bowed low to the ground. 3He said, “If I have found favor in your eyes, my lord, do not pass your servant by. 4Let a little water be brought, and then you may all wash your feet and rest under this tree. 5Let me get you something to eat, so you can be refreshed and then go on your way—now that you have come to your servant.” “Very well,” they answered, “do as you say.” 6So Abraham hurried into the tent to Sarah. “Quick,” he said, “get three seahs of the finest flour and knead it and bake some bread.” 7Then he ran to the herd and selected a choice, tender calf and gave it to a servant, who hurried to prepare it.
