God’s Covenant with Abram

15 After these things the word of the Lord came to Abram in a vision, “Do not be afraid, Abram, I am your shield; your reward shall be very great.” ² But Abram said, “O Lord God, what will you give me, for I continue childless, and the heir of my house is Eliezer of Damascus?”^{[a] 3} And Abram said, “You have given me no offspring, and so a slave born in my house is to be my heir.” ⁴ But the word of the Lord came to him, “This man shall not be your heir; no one but your very own issue shall be your heir.” ⁵ He brought him outside and said, “Look toward heaven and count the stars, if you are able to count them.” Then he said to him, “So shall your descendants be.” ⁶ And he believed the Lord; and the Lord^[b] reckoned it to him as righteousness.

³ Then Abram fell on his face; and God said to him, ⁴ “As for me, this is my covenant with you: You shall be the ancestor of a multitude of nations. ⁵ No longer shall your name be Abram,^[a] but your name shall be Abraham;^[b] for I have made you the ancestor of a multitude of nations.

¹⁵ God said to Abraham, “As for Sarai your wife, you shall not call her Sarai, but Sarah shall be her name. ¹⁶ I will bless her, and moreover I will give you a son by her. I will bless her, and she shall give rise to nations; kings of peoples shall come from her.”

The Birth of Isaac

21 The Lord dealt with Sarah as he had said, and the Lord did for Sarah as he had promised. ² Sarah conceived and bore Abraham a son in his old age, at the time of which God had spoken to him. ³ Abraham gave the name Isaac to his son whom Sarah bore him. ⁴ And Abraham circumcised his son Isaac when he was eight days old, as God had commanded him. ⁵ Abraham was a hundred years old when his son Isaac was born to him. ⁶ Now Sarah said, “God has brought laughter for me; everyone who hears will laugh with me.” ⁷ And she said, “Who would ever have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age.”
