Genesis 25:21-26American Standard Version (ASV)
21 And Isaac entreated Jehovah for his wife, because she was barren: and Jehovah was entreated of him, and Rebekah his wife conceived. 22 And the children struggled together within her; and she said, If it be so, [a]wherefore do I live? And she went to inquire of Jehovah. 23 And Jehovah said unto her,
Two nations are in thy womb,
24 And when her days to be delivered were fulfilled, behold, there were twins in her womb. 25 And the first came forth [b]red, all over like a hairy garment; and they called his name Esau. 26 And after that came forth his brother, and his hand had hold on Esau’s heel; and his name was called [c]Jacob: and Isaac was threescore years old when she bare them.
