1 Chronicles 5:7

(7) And his brethren by their families.—“And his fellow-tribesmen, each after his clan (Numbers 2:34), in the registration after their pedigrees, were the chief, Jeiel, and Zechariah.” Jeiel was the chief of the second Reubenite clan, as Beerah of the first. Zechariah and Bela were heads of the other chief houses. It appears that these four chieftains correspond to the four divisions of Reuben mentioned in 1 Chronicles 5:3.Numbers 26:7; Numbers 26:7 says expressly that “the Hanochite, the Palluite, the Hezronite, and the Carmite” were “the clans of the Reubenite.”
