18 And the Lord appeared to him by the ^(A)oaks^[a] of Mamre, as he sat at the door of his tent in the heat of the day. ² He lifted up his eyes and looked, and behold, three men were standing in front of him. ^(B)When he saw them, he ran from the tent door to meet them and bowed himself to the earth ³ and said, “O Lord,^[b] if I have found favor in your sight, do not pass by your servant. ⁴ Let a ^(C)little water be brought, and wash your feet, and rest yourselves under the tree, ⁵ while I bring a morsel of bread, that ^(D)you may refresh yourselves, and after that you may pass on—^(E)since you have come to your servant.” So they said, “Do as you have said.” ⁶ And Abraham went quickly into the tent to Sarah and said, “Quick! Three seahs^[c] of fine flour! Knead it, and make cakes.” ⁷ And Abraham ran to the herd and took a calf, tender and good, and gave it to a young man, who prepared it quickly. ⁸ Then 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 Sarah your wife?” And he said, “She is ^(F)in the tent.” ¹⁰ The Lord said, “I will surely return to you ^(G)about this time next year, and ^(H)Sarah your wife shall have a son.” And Sarah was listening at the tent door behind him. ¹¹ Now ^(I)Abraham and Sarah were old, advanced in years. The way of women had ceased to be with Sarah. ^12 (J)So Sarah laughed to herself, saying, ^(K)“After I am worn out, and ^(L)my lord is old, shall I have pleasure?” ¹³ The Lord said to Abraham, “Why did Sarah laugh and say, ‘Shall I indeed bear a child, now that I am old?’ ^14 (M)Is anything too hard^[d] for the Lord? ^(N)At the appointed time I will return to you, about this time next year, and Sarah shall have a son.” ¹⁵ But Sarah denied it,^[e] saying, “I did not laugh,” for she was afraid. He said, “No, but you did laugh.”

The Birth of Isaac

21 The Lord ^(A)visited Sarah as he had said, and the Lord did to Sarah ^(B)as he had promised. ² And Sarah ^(C)conceived and bore Abraham a son in his old age ^(D)at the time of which God had spoken to him. ³ Abraham called the name of his son who was born to him, whom Sarah bore him, ^(E)Isaac.^{[a] 4} And Abraham ^(F)circumcised his son Isaac when he was eight days old, ^(G)as God had commanded him. ^5 (H)Abraham was a hundred years old when his son Isaac was born to him. ⁶ And Sarah said, ^(I)“God has made laughter for me; everyone who hears will laugh over me.” ⁷ And she said, “Who would have said to Abraham that Sarah would nurse children? ^(J)Yet I have borne him a son in his old age.”
