Genesis 25:19-26

Young's Literal Translation

¹⁹ And these [are] births of Isaac, Abraham's son: Abraham hath begotten Isaac;

²⁰ and 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.

²¹ And Isaac maketh entreaty to Jehovah before his wife, for she [is] barren: and Jehovah is entreated of him, and Rebekah his wife conceiveth,

²² and the children struggle together within her, and she saith, `If [it is] right -- why [am] I thus?' and she goeth to seek Jehovah.

²³ And 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.'

²⁴ And her days to bear are fulfilled, and lo, twins [are] in her womb;

²⁵ and the first cometh out all red as a hairy robe, and they call his name Esau;

²⁶ and 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.
