The 'protestant rewrite' happens to be more consistent between Genesis and this passage here so it seems that the Douay-Rheims is the one that falls short.
Pffft. As the DR footnote points out, the Church Fathers were divided based on variants in the text and there's no question of being "more" or "less" consistent with Genesis. Question is the text of Genesis itself. And I'll take St. Jerome's reading of the text over yours (or that of the Prots) any day. St. Jerome used he Septuagint, which likely more accurately reflects the original Hebrew than the Hebrew texts that survived (which in many places were deliberately altered to expunge Christian reading of the OT).
