31As for the Hebronites: Jerijah was the chief of the Hebronites according to the genealogical records of their families. In the fortieth year of David’s reign a search was made and found in them were valiant men in Jazer of Gilead.

32His relatives, 2,700 men of valor, were heads of clans whom King David had appointed over the Reubenites, the Gadites and the half-tribe of the Manasseh in every matter pertaining to God and the affairs of the king.
