²⁴ Abraham was ninety-nine years old when he was circumcised in the flesh of his foreskin.^(A)

¹¹ He received the sign of circumcision as a seal of the righteousness that he had by faith^[a] while he was still uncircumcised. The purpose was to make him the ancestor of all who believe^[b] without being circumcised and who thus have righteousness reckoned to them,^(A)

¹⁹ He did not weaken in faith when he considered his own body, which was already^[a] as good as dead (for he was about a hundred years old), and the barrenness of Sarah’s womb.^{(A) 20} No distrust made him waver concerning the promise of God, but he grew strong in his faith as he gave glory to God,

¹⁷ Then Abraham fell on his face and laughed and said to himself, “Can a child be born to a man who is a hundred years old? Can Sarah, who is ninety years old, bear a child?”^(A)

The Sign of the Covenant

17 When Abram was ninety-nine years old, the Lord appeared to Abram and said to him, “I am God Almighty;^[a] walk before me, and be blameless.^(A)

⁴ So Abram went, as the Lord had told him, and Lot went with him. Abram was seventy-five years old when he departed from Haran.^(A)
