Hodesh: In the preceding verse it is said that "Hushim and Baara were his wives;" and here it said, "he begat of Hodesh his wife," etc; and then in the 1 Chronicles 8:11, his children by Hushim are mentioned, but not a word of Baara.
It is probable, therefore, that Hodesh was another name for Baara; and this is asserted by the Targumist: "And he begat of Baara, that is, of Chodesh, his wife, so called because he espoused her anew."
