Genesis 18:4

And the LORD appeared unto him in the plains of Mamre: and he sat in the tent door in the heat of the day;

And he lift up his eyes and looked, and, lo, three men stood by him: and when he saw them, he ran to meet them from the tent door, and bowed himself toward the ground,

And said, My Lord, if now I have found favour in thy sight, pass not away, I pray thee, from thy servant:

And I will fetch a morsel of bread, and comfort ye your hearts; after that ye shall pass on: for therefore are ye come to your servant. And they said, So do, as thou hast said.
