18The Lord appeared to Abraham* by the oaks* of Mamre, as he sat at the entrance of his tent in the heat of the day. 2He looked up and saw three men standing near him. When he saw them, he ran from the tent entrance to meet them, and bowed down to the ground. 3He said, ‘My lord, if I find favour with you, do not pass by your servant. 4Let a little water be brought, and wash your feet, and rest yourselves under the tree. 5Let me bring a little bread, that you may refresh yourselves, and after that you may pass on—since you have come to your servant.’ So they said, ‘Do as you have said.’ 6And Abraham hastened into the tent to Sarah, and said, ‘Make ready quickly three measures* of choice flour, knead it, and make cakes.’ 7Abraham ran to the herd, and took a calf, tender and good, and gave it to the servant, who hastened to prepare it.8Then he took curds and milk and the calf that he had prepared, and set it before them; and he stood by them under the tree while they ate.
9 They said to him, ‘Where is your wife Sarah?’ And he said, ‘There, in the tent.’ 10Then one said, ‘I will surely return to you in due season, and your wife Sarah shall have a son.’ And Sarah was listening at the tent entrance behind him. 11Now Abraham and Sarah were old, advanced in age; it had ceased to be with Sarah after the manner of women. 12So Sarah laughed to herself, saying, ‘After I have grown old, and my husband is old, shall I have pleasure?’ 13The Lord said to Abraham, ‘Why did Sarah laugh, and say, “Shall I indeed bear a child, now that I am old?”14Is anything too wonderful for the Lord? At the set time I will return to you, in due season, and Sarah shall have a son.’
