Adam Clarke on 1 Chronicles 8:9

He begat of Hodesh his wife - In the preceding verse it is said that Hushim and Baara were his wives; and here it is said he begat of Hodesh his wife, etc. And then his children by Hushim are mentioned, but not a word of Baara! It is likely therefore that Hodesh was another name for Baara, and this is asserted by the Targum: And he begot of Baara, that is Chodesh, his wife; so called because he espoused her anew. It is supposed that he had put her away before, and now remarried her.
