19 Now these are the generations of Abraham's son Isaac: 20 Isaac was forty years old when he took Rebekah, the daughter of Bethuel the Aramaean of Paddan-aram, and the sister of Laban the Aramaean, to be his wife. 21 Isaac made prayer to the Lord for his wife because she had no children; and the Lord gave ear to his prayer, and Rebekah became with child. 22 And the children were fighting together inside her, and she said, If it is to be so, why am I like this? So she went to put her question to the Lord. 23 And the Lord said to her, Two nations are in your body, and two peoples will come to birth from you: the one will be stronger than the other, and the older will be the servant of the younger. 24 And when the time came for her to give birth, there were two children in her body. 25 And the first came out red from head to foot like a robe of hair, and they gave him the name of Esau. 26 And after him, his brother came out, gripping Esau's foot; and he was named Jacob: Isaac was sixty years old when she gave birth to 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?
