Twins in the Bible

Genesis 25:24-26 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.

Genesis 38:27-30 And it came to pass in the time of her travail, that, behold, twins were in her womb. 28 And it came to pass, when she travailed, that the one put out his hand: and the midwife took and bound upon his hand a scarlet thread, saying, This came out first. 29 And it came to pass, as he drew back his hand, that, behold, his brother came out: and she said, How hast thou broken forth? this breach be upon thee: therefore his name was called Pharez. 30 And afterward came out his brother, that had the scarlet thread upon his hand: and his name was called Zarah.
