19 These are the descendants of Isaac, Abraham's son: Abraham was the father of Isaac, 20 and Isaac was forty years old when he married Rebekah, daughter of Bethuel the Aramean of Paddan-aram, sister of Laban the Aramean. 21 Isaac prayed to the Lord for his wife, because she was barren; and the Lord granted his prayer, and his wife Rebekah conceived. 22 The children struggled together within her; and she said, "If it is to be this way, why do I live?" So she went to inquire of the Lord. 23 And the Lord said to her, "Two nations are in your womb, and two peoples born of you shall be divided; the one shall be stronger than the other, the elder shall serve the younger." 24 When her time to give birth was at hand, there were twins in her womb. 25 The first came out red, all his body like a hairy mantle; so they named him Esau. 26 Afterward his brother came out, with his hand gripping Esau's heel; so he was named Jacob. Isaac was sixty years old when she bore them.

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?
