The sons of the wife of Hodiah, the sister of Naham, were the fathers of Keilah the Garmite and Eshtemoa the Maacathite.
We may observe in these verses, 1. That here is a whole family of craftsmen, handicraft tradesmen, that applied themselves to all sorts of manufactures, in which they were ingenious and industrious above their neighbours, Ch1 4:14. There was a valley where they lived which was, from them, called the valley of craftsmen. Those that are craftsmen are not therefore to be looked upon as mean men.

And the sons of his wife Hodiah,.... Another wife of Mered. Hillerus (c) takes her to be the same with Jehudijah, Ch1 4:18, though some (d) take Hodiah to be the name of a man, and read the words, "and the sons of the wife of Hodiah"; which wife of Hodiah was the sister of Naham; or rather Achotnaham, we render the sister of Naham...
1Ch 4:17-19 Ezra, whose four sons are enumerated, is likewise unknown. The singular בּן is peculiar, but has analogies in 1Ch 3:19, 1Ch 3:21, and 1Ch 3:23. Of the names of his sons, Jether and Epher again occur, the former in 1Ch 2:53, and the latter in 1Ch 1:33 and 1Ch 5:24, but in other families. Jalon, on the contrary, is found only here.
