Genesis 18:8-10

Darby Translation

⁸ And he took thick and sweet milk, and the calf that he had dressed, and set [it] before them; and he stood before them under the tree, and they ate.

⁹ And they said to him, Where is Sarah thy wife? And he said, Behold, in the tent.

¹⁰ And he said, I will certainly return to thee at [this] time of the year, and behold, Sarah thy wife shall have a son. And Sarah was listening at the tent-door, which was behind him.
