Genesis 25:21-23 And Isaac entreated the LORD for his wife, because she was barren: and the LORD was entreated of him, and Rebekah his wife conceived.

AKJV⁽ⁱ⁾ ²¹ And Isaac entreated the LORD for his wife, because she was barren: and the LORD was entreated of him, and Rebekah his wife conceived. ²² And the children struggled together within her; and she said, If it be so, why am I thus? And she went to inquire of the LORD. ²³ And the LORD said to her, Two nations are in your womb, and two manner of people shall be separated from your bowels; and the one people shall be stronger than the other people; and the elder shall serve the younger.
