Genesis 25:21-23 Douay-Rheims 1899 American Edition (DRA)
21 And Isaac besought the Lord for his wife, because she was barren; and he heard him, and made Rebecca to conceive.
22 But the children struggled in her womb: and she said: If it were to be so with me, what need was there to conceive? And she went to consult the Lord.
23 And he answering said: Two nations are in thy womb, and two peoples shall be divided out of thy womb, and one people shall overcome the other, and the elder shall serve the younger.
