John Gill 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
Not he that was a judge in Israel, (Judges 3:15) but perhaps a son of Huram the last mentioned; for not the three last are his sons, as some think, but the three following in the next verse; what follows being to be read in a parenthesis:

(these are the heads of the fathers of the inhabitants of Geba; )
a city in the tribe of Benjamin, (Joshua 18:24) namely, those sons of Ehud, after mentioned, were principal men in that tribe, and chief of the inhabitants of the city of Geba:

and they removed them to Manahath ;
the name of a country referred to in (1 Chronicles 2:52 1 Chronicles 2:54) according to Jarchi, which was in the tribe of Judah; Geba being too small, either the inhabitants of Geba removed them, or they removed themselves, or their fathers removed them, (1 Chronicles 8:7) , or it may be read impersonally, they were removed thither for the sake of a better habitation; the Targum adds,

``to the land of the house of Esau,''

to Edom; which is not likely.
