Genesis 17:15-Genesis 18:21 - Isaac's Birth Promised

¹⁵ Then God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai (my princess), but her name will be Sarah (Princess). ¹⁶ I will bless her, and indeed I will also give you a son by her. Yes, I will bless her, and she shall be a mother of nations; kings of peoples will come from her.”

¹⁷ Then Abraham fell on his face and laughed, and said in his heart, “Shall a child be born to a man who is a hundred years old? And shall Sarah, who is ninety years old, bear a child?” ¹⁸ And Abraham said to God, “Oh, that Ishmael [my firstborn] might live before You!”

¹⁹ But God said, “No, Sarah your wife shall bear you a son indeed, and you shall name him Isaac (laughter); and I will establish My covenant with him for an everlasting covenant and with his descendants after him. ²⁰ As for Ishmael, I have heard and listened to you; behold, I will bless him, and will make him fruitful and will greatly multiply him [through his descendants]. He will be the father of twelve princes (chieftains, sheiks), and I will make him a great nation. ²¹ But My covenant [My promise, My solemn pledge], I will establish with Isaac, whom Sarah will bear to you at this time next year.” ²² And God finished speaking with him and went up from Abraham.

²³ Then Abraham took Ishmael his son, and all the servants who were born in his house and all who were purchased with his money, every male among the men of Abraham’s household, and circumcised the flesh of their foreskin the very same day, as God had said to him. ²⁴ So Abraham was ninety-nine years old when he was circumcised. ²⁵ And Ishmael his son was thirteen years old when he was circumcised. ²⁶ On the very same day Abraham was circumcised, as well as Ishmael his son. ²⁷ All the men [servants] of his household, both those born in the house and those purchased with money from a foreigner, were circumcised along with him [as the sign of God’s covenant with Abraham].

¹ Now the Lord appeared to Abraham by the terebinth trees of Mamre [in Hebron], while he was sitting at the tent door in the heat of the day. ² When he raised his eyes and looked up, behold, three men were standing [a little distance] from him. When he saw them, he ran from the tent door to meet them and bowed down [with his face] to the ground, ³ and Abraham said, “My lord, if now I have found favor in your sight, please do not pass by your servant [without stopping to visit]. ⁴ Please let a little water be brought [by one of my servants] and [you may] wash your feet, and recline and rest comfortably under the tree. ⁵ And I will bring a piece of bread to refresh and sustain you; after that you may go on, since you have come to your servant.” And they replied, “Do as you have said.”

⁶ So Abraham hurried into the tent to Sarah, and said, “Quickly, get ready three measures of fine meal, knead it and bake cakes.” ⁷ Abraham also ran to the herd and brought a calf, tender and choice, and he gave it to the servant [to butcher], and he hurried to prepare it. ⁸ Then he took curds and milk and the calf which he had prepared, and set it before the men; and he stood beside them under the tree while they ate.

⁹ Then they said to him, “Where is Sarah your wife?” And he said, “There, in the tent.”

¹⁰ He said, “I will surely return to you at this time next year; and behold, Sarah your wife will have a son.” And Sarah was listening at the tent door, which was behind him.

¹¹ Now Abraham and Sarah were old, well advanced in years; she was past [the age of] childbearing. ¹² So Sarah laughed to herself [when she heard the Lord’s words], saying, “After I have become old, shall I have pleasure and delight, my lord (husband) being also old?”

¹³ And the Lord asked Abraham, “Why did Sarah laugh [to herself], saying, ‘Shall I really give birth [to a child] when I am so old?’ ¹⁴ Is anything too difficult or too wonderful for the Lord? At the appointed time, when the season [for her delivery] comes, I will return to you and Sarah will have a son.”

¹⁵ Then Sarah denied it, saying, “I did not laugh”; because she was afraid. And He (the Lord) said, “No, but you did laugh.”

¹⁶ Then the men got up from there, and looked toward Sodom; and Abraham walked with them to send them on the way. ¹⁷ The Lord said, “Shall I keep secret from Abraham [My friend and servant] what I am going to do, ¹⁸ since Abraham is destined to become a great and mighty nation, and all the nations of the earth will be blessed through him? ¹⁹ For I have known (chosen, acknowledged) him [as My own], so that he may teach and command his children and [the sons of] his household after him to keep the way of the Lord by doing what is righteous and just, so that the Lord may bring upon Abraham what He has promised him.” ²⁰ And the Lord said, “The outcry [of the sin] of Sodom and Gomorrah is indeed great, and their sin is exceedingly grave. ²¹ I will go down now, and see whether they have acted [as vilely and wickedly] as the outcry which has come to Me [indicates]; and if not, I will know.”
