Charles Ellicott Commentary 1 Chronicles 25:3

"Of Jeduthun; the sons of Jeduthun: Gedaliah, and Zeri, and Jeshaiah, Hashabiah, and Mattithiah, six, under the hands of their father Jeduthun with the harp, who prophesied in giving thanks and praising Jehovah." — 1 Chronicles 25:3 (ASV)

Of Jeduthun: the sons of Jeduthun. —Rather, To Jeduthun (that is, belonging to the guild so named): the sons of Jeduthun were Gedaliah, etc.

Zeri. —The “Izri” of 1 Chronicles 25:11 is probably correct. (Compare to Numbers 26:49.) This error is as old as the ancient versions.

Six. —Only five names are now found in the text; the name “Shimei” (1 Chronicles 25:17) is missing. This is the only name in 1 Chronicles 25:9–31 that does not occur in 1 Chronicles 25:2–4. The Alexandrian Septuagint inserts the name between Jeshaiah and Hashabiah.

Jeshaiah. —Elsewhere spelled Isaiah.

Under the hands (see last verse) of their father Jeduthun, who prophesied with a harp. —Literally, according to the Hebrew punctuation, at the hands of their father Jeduthun, with the lute (that is, provided with lutes, 1 Chronicles 15:16), who prophesied (or was to prophesy) to give thanks and praise to Jehovah. (Compare to 1 Chronicles 16:4).

At the hands of their father. —Under the direction of their conductor.
