The sons of Jehallelel: Ziph, Ziphah, Tiria, and Asarel.
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.
Commenting on 1 Chronicles 4:11-23
And the sons of Jehaleleel,.... Who probably was the son of Uknaz: Ziph, and Ziphah, Tiria, and Asareel; there were two cities in the tribe of Judah of the name of Ziph, Jos 15:24, which might be called from these men, or from Ziph in Ch1 2:42.
1Ch 4:16 Sons of Jehaleleel, a man not elsewhere mentioned. Ziph, Ziphah, etc., are met with only here. There is no strong reason for connecting the name זיף with the towns of that name, Jos 15:24, Jos 15:55.
