24 And when her days to be delivered were fulfilled, behold, there were twins in her womb. 25 And the first came out red, all over like an hairy garment; and they called his name Esau. 26 And after that came his brother out, and his hand took hold on Esau's heel; and his name was called Jacob: and Isaac was threescore years old when she bare them.
