Genesis 18:2–15

²And he lifted up his eyes and saw, and behold, three men standing near him. And when he saw them, he ran to meet them from the tent-door, and bowed himself to the earth, ³and said, Lord, if now I have found favour in thine eyes, pass not away, I pray thee, from thy servant. ⁴Let now a little water be fetched, that ye may wash your feet, and rest yourselves under the tree. ⁵And I will fetch a morsel of bread; and refresh yourselves; after that ye shall pass on; for therefore have ye passed on towards your servant. And they said, So do as thou hast said. ⁶And Abraham hastened into the tent to Sarah, and said, Knead quickly three seahs of wheaten flour, and make cakes. ⁷And Abraham ran to the herd, and took a calf tender and good, and gave it to the attendant; and he hasted to dress it. ⁸And 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.

⁹And they said to him, Where is Sarah thy wife? And he said, Behold, in the tent. ¹⁰And 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. ¹¹Now Abraham and Sarah were old and advanced in age: it had ceased to be with Sarah after the manner of women. ¹²And Sarah laughed within herself, saying, After I am become old, shall I have pleasure, and my lord old? ¹³And Jehovah said to Abraham, Why is this, that Sarah laughs, saying, Shall I indeed bear, when I am become old? ¹⁴Is any matter too wonderful for Jehovah? At the time appointed I will return to thee, at this time of the year, and Sarah shall have a son. ¹⁵And Sarah denied, saying, I did not laugh; for she was afraid. And he said, No; but thou didst laugh.
