This is the account of the family of Issac, the son of Abraham. When Isaac was 40 years old; he married Rebekah, daughter of Bethuel the Armean from Paddan-aram and the sister of Laban and Aramean.
Isaac pleaded with the Lord on behalf of his wife, because she was unable to have children. The Lord answered Isaac’s prayer, and Rebekah became pregnant with twins. But the two children struggled with each other in her womb. So she went to the Lord about it. “Why is this happening to me?” she asked.
And the Lord told her, “The sons in your womb will become two nations. From the very beginning, the two nations will be rivals. One nation will be stronger than the other; and your older son will serve your younger son.”
And then the time came to give birth, Rebekah discovered that she did indeed have twins! The first one was veery red at birth and covered with thick hair like a fur coat. So they named him Esaus. The other twin was born with his hand grasping Esau’s heel. So they named him Jacob. Isaac was sixty years old when the twins were born. (vv. 19-26, NLT)
