Genesis
Chapters 38:27-30
Revised Version 1885
27And it came to pass in the time of her travail, that, behold, twins were in her womb.
28And it came to pass, when she travailed, that one put out a hand: and the midwife took and bound upon his hand a scarlet thread, saying, This came out first.
29And it came to pass, as he drew back his hand, that, behold, his brother came out: and she said, Wherefore hast thou made a breach for thyself? therefore his name was called Perez.
30And afterward came out his brother, that had the scarlet thread upon his hand: and his name was called Zerah.
