Genesis 38:29-30

Young's Literal Translation

²⁹ And it cometh to pass as he draweth back his hand, that lo, his brother hath come out, and she saith, `What! thou hast broken forth -- on thee [is] the breach;' and he calleth his name Pharez;

³⁰ and afterwards hath his brother come out, on whose hand [is] the scarlet thread, and he calleth his name Zarah.
