Genesis 25:19-26 New American Bible (Revised Edition) (NABRE)
Birth of Esau and Jacob. 19 [a]These are the descendants of Isaac, son of Abraham; Abraham begot Isaac. 20 Isaac was forty years old when he married Rebekah, the daughter of Bethuel the Aramean of Paddan-aram[b] and the sister of Laban the Aramean. 21 Isaac entreated the Lord on behalf of his wife, since she was sterile. The Lord heard his entreaty, and his wife Rebekah became pregnant. 22 But the children jostled each other in the womb so much that she exclaimed, “If it is like this,[c] why go on living!” She went to consult the Lord, 23 and the Lord answered her:
Two nations are in your womb,
24 When the time of her delivery came, there were twins in her womb. 25 The first to emerge was reddish,[e] and his whole body was like a hairy mantle; so they named him Esau. 26 Next his brother came out, gripping Esau’s heel;[f] so he was named Jacob. Isaac was sixty years old when they were born.
