For an odious woman when she is married; and an handmaid that is heir to her mistress.
For an odious (woman) when she is married - for by her bad temper and ways she makes herself unbearable to her husband, her domestics, and her neighbours. Cartwright and Maurer explain: when a man had two wives, the one beloved, the other comparatively hated (cf. Deuteronomy 21:15), if the latter be made by her husband the beloved wife, she is sure to behave imperiously, because of the former contumely she bare. I prefer the English version.
And an handmaid ... heir to her mistress - the lower sunk in grade she was before the more insolent she will be when she has gotten a fortune. Gesenius, after the Septuagint, translates, 'an handmaid, when she has expelled; i:e. succeeded into the place of her mistress.' So the Syriac. But the Vulgate and Chaldaic support the English version.
