Charles Ellicott Commentary 1 Chronicles 26:30

"Of the Hebronites, Hashabiah and his brethren, men of valor, a thousand and seven hundred, had the oversight of Israel beyond the Jordan westward, for all the business of Jehovah, and for the service of the king." — 1 Chronicles 26:30 (ASV)

And of the Hebronites, Hashabiah. —Rather, As to the Hebronites, Hashabiah, and his kinsmen, sons of valour (1 Chronicles 26:7), a thousand and seven hundred, were charged with (Hebrew, over) the supervision of Israel on the other side of the Jordan, westward, for all the work of Iahweh and for the service of the king.

Officers. —Pĕquddah (oversight, superintendence). Vulgate, praeerant Israeli: Septuagint, ἐπὶ τῆς ἐπισκέψεως τοῦ Ἰσραήλ. (See 1 Chronicles 23:11; 1 Chronicles 24:19 for another meaning of the word.)

Hashabiah. —A Kohathite of this name is not mentioned elsewhere.

On this side Jordan. —Rather, on the other side (‘ēber): the western side of the river is so called in Joshua 5:1; Joshua 22:7. The use of this expression here seems to imply that the source on which the chronicle here depends was written in some locality east of the Jordan, perhaps at Babylon.
