Matthew Henry Presbyterian @wholebiblehenry

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 Kenaz,.... Who was either the son of Chelub, or of Eshton: Othniel, and Seraiah; the first of these is he who is mentioned, Jos 15:17 and was the first judge in Israel: and the son of Othniel, Hathath; and the next mentioned.

the sons of Kenaz--the grandfather of Caleb, who from that relationship is called a Kenezite (Num 32:12).
