Genesis 18:3

1The LORD appeared to him by the oaks of Mamre, as he sat in the tent door in the heat of the day.

2He lifted up his eyes and looked, and saw that three men stood near him. When he saw them, he ran to meet them from the tent door, and bowed himself to the earth,

3and said, “My lord, if now I have found favor in your sight, please don’t go away from your servant.

4Now let a little water be fetched, wash your feet, and rest yourselves under the tree.

5I 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.”
