19 This is the account of the family of Isaac, the son of Abraham. 20 When Isaac was forty years old, he married Rebekah, the daughter of Bethuel the Aramean from Paddan-aram and the sister of Laban the Aramean. 21 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. 22 But the two children struggled with each other in her womb. So she went to ask the Lord about it. "Why is this happening to me?" she asked. 23 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." 24 And when the time came to give birth, Rebekah discovered that she did indeed have twins! 25 The first one was very red at birth and covered with thick hair like a fur coat. So they named him Esau. 26 Then 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.

Isaac seems not to have been much tried, but to have spent his days in quietness. Jacob and Esau were prayed for; their parents, after being long childless, obtained them by prayer. The fulfilment of God's promise is always sure, yet it is often slow. The faith of believers is tried, their patience exercised, and mercies long waited for are more welcome when they come. Isaac and Rebekah kept in view the promise of all nations being blessed in their posterity, therefore were not only desirous of children, but anxious concerning every thing which seemed to mark their future character. In all our doubts we should inquire of the Lord by prayer. In many of our conflicts with sin and temptation, we may adopt Rebekah's words, "If it be so, why am I thus?" If a child of God, why so careless or carnal? If not a child of God, why so afraid of, or so burdened with sin?
