Genesis 38:30 WEB

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  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  Afterward his brother came out, that had the scarlet thread on his hand, and his name was called Zerah.{Zerah means 'scarlet' or 'brightness.'}
