Genesis 17:1-27, NLT
Abram Is Named Abraham
1When Abram was ninety-nine years old, the Lord appeared to him and said, “I am El-Shaddai—‘God Almighty.’ Serve me faithfully and live a blameless life.
3At this, Abram fell face down on the ground. Then God said to him,
7“I will confirm my covenant with you and your descendants*17:7 Hebrew seed; also in 17:7b, 8, 9, 10, 19. after you, from generation to generation. This is the everlasting covenant: I will always be your God and the God of your descendants after you.
The Mark of the Covenant
9Then God said to Abraham, “Your responsibility is to obey the terms of the covenant. You and all your descendants have this continual responsibility.
Sarai Is Named Sarah
15Then God said to Abraham, “Regarding Sarai, your wife—her name will no longer be Sarai. From now on her name will be Sarah.*17:15 Sarai and Sarah both mean “princess”; the change in spelling may reflect the difference in dialect between Ur and Canaan.
17Then Abraham bowed down to the ground, but he laughed to himself in disbelief. “How could I become a father at the age of 100?” he thought. “And how can Sarah have a baby when she is ninety years old?”
19But God replied, “No—Sarah, your wife, will give birth to a son for you. You will name him Isaac,*17:19 Isaac means “he laughs.” and I will confirm my covenant with him and his descendants as an everlasting covenant.
23On that very day Abraham took his son, Ishmael, and every male in his household, including those born there and those he had bought. Then he circumcised them, cutting off their foreskins, just as God had told him.
