Charles Ellicott Commentary 1 Chronicles 7:34

"And the sons of Shemer: Ahi, and Rohgah, Jehubbah, and Aram." — 1 Chronicles 7:34 (ASV)

Shamer (pausal form of Shemer) is probably identical with Shomer, the second son of Heber (1 Chronicles 7:32).

Jehubbah. —The Hebrew margin has we-Hubbah, “and Hubbah,” which is correct according to the prevailing form of this list (and before each name).

Aram is the ordinary name of the Syrians east and west of the Euphrates. It may here designate a clan of half-Aramean extraction.

(35–39) And the sons of his brother Helem. —Apparently these are the offshoots of Helem, “brother” of Sheraer-Shomer. If we construe brother in the strict sense, we must assume that Helem is the same as Hotham (1 Chronicles 7:32), and that one or the other name is corrupt. But Helem may be the name of another chief house of Asher not directly connected with that of Heber. The brotherhood then would be that of the tribe, not of the clan or family.
