Charles Ellicott Commentary 1 Chronicles 8:6

"And these are the sons of Ehud: these are the heads of fathers` [houses] of the inhabitants of Geba, and they carried them captive to Manahath:" — 1 Chronicles 8:6 (ASV)

And these are the sons of Ehud. — The Authorised Version makes no distinction between this Ehud and Ehud son of Gera, the famous Benjamite judge (Judges 3:15). The difference in the Hebrew is so slight, that perhaps we may assume an original identity of the two names. In that case we get a link between the sons of Ehud and the house of Gera (1 Chronicles 8:5). Others identify the present Ehud with Abihud (1 Chronicles 8:3), which is possibly correct: (Compare Nadab-Abinadab, Dan and Abidan, (Numbers 1:11)).

These are the heads of the fathers. — Heads of father-houses, i.e., groups of kindred families or clans. The Hebrew text of the rest of this verse and of 1 Chronicles 8:7–8 is unusually obscure, partly owing to the construction, but chiefly because of the historical allusions which are no longer explicable with any certainty. Most interpreters assume a parenthesis after the words “and these are the sons of Ehud,” extending to the words “he removed them,” (1 Chronicles 8:7).

Uzza and Ahihud are then “the sons of Ehud” referred to in (1 Chronicles 8:6).

Removed them. — Rather, carried them captive, or transported them. The same expression denotes the Babylonian exile or transportation, and was used in (1 Chronicles 5:26) of the Assyrian removal of the trans-Jordanian tribes.
