Birth of Isaac Promised

18 Now ^(A)the Lord appeared to ^[a]Abraham by the ^[b](B)oaks of Mamre, while he was sitting at the tent door in the heat of the day. ² When he raised his eyes and looked, behold, three ^(C)men were standing opposite him; and when he saw them, he ran from the tent door to meet them and bowed down to the ground, ³ and said, “^[c]My Lord, if now I have found favor in Your sight, please do not ^[d]pass Your servant by. ⁴ Please let a little water be brought and ^(D)wash ^[e]your feet, and make yourselves comfortable under the tree; ⁵ and I will ^[f](E)bring a piece of bread, so that you may ^[g]refresh yourselves; after that you may go on, since you have ^[h]visited your servant.” And they said, “So do as you have said.” ⁶ So Abraham hurried into the tent to Sarah, and said, “^[i]Quickly, prepare three ^[j]measures of fine flour, knead it, and make bread cakes.” ⁷ Abraham also ran to the herd, and took a tender and ^[k]choice calf and gave it to the servant, and he hurried to prepare it. ⁸ He took curds and milk and the calf which he had prepared, and set it before them; and he was standing by them under the tree ^[l]as they ate.

⁹ Then they said to him, “Where is your wife Sarah?” And he said, “There, in the tent.” ¹⁰ He said, “^(F)I will certainly return to you ^[m]at this time next year; and behold, your wife Sarah will have a son.” And Sarah was listening at the tent door, which was behind him. ¹¹ Now ^(G)Abraham and Sarah were old, advanced in age; Sarah was ^(H)past ^[n]childbearing. ¹² So Sarah laughed ^[o]to herself, saying, “^(I)After I have become old, am I to have pleasure, my ^(J)lord being old also?” ¹³ But the Lord said to Abraham, “Why did Sarah laugh, saying, ‘Shall I actually give birth to a child, when I am so old?’ ^14 (K)Is anything too ^[p]difficult for the Lord? At the ^(L)appointed time I will return to you, ^[q]at this time next year, and Sarah will have a son.” ¹⁵ Sarah denied it, however, saying, “I did not laugh”; for she was afraid. And He said, “No, but you did laugh.”

Isaac Is Born

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