John Gill Commentary 1 Chronicles 8:9

"And he begat of Hodesh his wife, Jobab, and Zibia, and Mesha, and Malcam," — 1 Chronicles 8:9 (ASV)

Ver. 9,10. And he begat of Hodesh his wife That is, he, I say, begat, namely, Shaharaim; the Targum makes this Hodesh to be the same with Baara, called so because she was newly espoused; but wrongly: the sons begotten of her were the seven following;

Jobab, Zibia, Mesha, Malcham, Jeuz, Shachia, and Mirma. These were his sons ; the sons of Shaharaim by his wife Hodesh:

heads of the fathers ; of the houses or families of their father.
