27 Ref It happened in the time of her travail, that behold, twins were in her womb.
28 It happened, when she travailed, that one put out a hand: and the midwife took and tied a scarlet thread on his hand, saying, "This came out first."
29 Ref It happened, as he drew back his hand, that behold, his brother came out, and she said, "Why have you made a breach for yourself?" Therefore his name was called Perez.{Perez means "breaking out."}
30 Ref Afterward his brother came out, that had the scarlet thread on his hand, and his name was called Zerah.{Zerah means "scarlet" or "brightness."}
