Genesis 18:6

2 And Abraham looked up and saw three men standing nearby. When he saw them, he ran from the entrance of his tent to meet them and bowed low to the ground.

3 “My lord,” said Abraham, “if I have found favor in your sight, please do not pass your servant by.

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

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

6 So Abraham hurried into the tent and said to Sarah, “Quick! Prepare three seahs of fine flour, knead it, and bake some bread.”

7 Meanwhile, Abraham ran to the herd, selected a tender and choice calf, and gave it to a servant, who hurried to prepare it.

8 Then Abraham brought curds and milk and the calf that had been prepared, and he set them before the men and stood by them under the tree as they ate.

9 “Where is your wife Sarah?” they asked. “There, in the tent,” he replied.

10 Then the LORD said, “I will surely return to you at this time next year, and your wife Sarah will have a son!” Now Sarah was behind him, listening at the entrance to the tent.
