Genesis chapter 25 opens with Abraham taking a second wife, Keturah. She bore him 6 sons, fulfilling God’s promise to make from him a multitude of peoples. Then, it moves to dispense of Ishmael’s genealogy. Showing that his twelve sons were also God’s fulfillment of His word to Abraham. And finally, it concentrates on Isaac. However, the final section begins focussing on the barrenness of Rebekah, Isaac’s wife. In time God responds to Isaac’s prayer and Rebekah conceives twins who quarrel from the womb, Esau and Jacob. These two young men grow up to be true to their names. But the center thought is the birthright, something that Jacob avidly desires but Esau considers worthless.
