Genesis 25:19–26

¹⁹And these are births of Isaac, Abraham’s son: Abraham hath begotten Isaac; ²⁰and Isaac is a son of forty years in his taking Rebekah, daughter of Bethuel the Aramaean, from Padan-Aram, sister of Laban the Aramaean, to him for a wife. ²¹And Isaac maketh entreaty to Jehovah before his wife, for she is barren: and Jehovah is entreated of him, and Rebekah his wife conceiveth, ²²and the children struggle together within her, and she saith, ‘If it is right—why am I thus?’ and she goeth to seek Jehovah. ²³And Jehovah saith to her, ‘Two nations are in thy womb, and two peoples from thy bowels are parted; and the one people than the other people is stronger; and the elder doth serve the younger.’ ²⁴And her days to bear are fulfilled, and lo, twins are in her womb; ²⁵and the first cometh out all red as a hairy robe, and they call his name Esau; ²⁶and afterwards hath his brother come out, and his hand is taking hold on Esau’s heel, and one calleth his name Jacob; and Isaac is a son of sixty years in her bearing them.
