And his brother Asaph, who stood on his right hand, even Asaph the son of Berachiah, the son of Shimea,

And his brother Asaph, who stood on his right hand, Asaph the son of Barachias, the son of Samaa.

And his brother Asaph, who is standing on his right, Asaph, son of Berachiah, son of Shimea,

And his brother Asaph, whose place was at his right hand, Asaph, the son of Berechiah, the son of Shimea,

And there was also his brother, Asaph, who was standing at his right, Asaph, the son of Berechiah, the son of Shimea,

His brother Asaph - Not "brother" in the ordinary sense of the term, since Asaph was the son of Berachiah, and a Gershonite, not a Kohathite. "Brother" here may mean "fellow-craftsman" (compare 1-Chronicles 25:7).

Asaph - This person, with Heman, the sons of Kora, Ethan, Jeduthun, etc., are celebrated in these books, and in the Psalm, for their skill in singing, and the part they performed in the public worship of God.
It is very likely that their singing was only a kind of recitative or chanting, such as we still find in the synagogues. It does not appear that God had especially appointed these singers, much less any musical instruments, (the silver trumpets excepted), to be employed in his service. Musical instruments in the house of God are, at least under the Gospel, repugnant to the spirit of Christianity, and tend not a little to corrupt the worship of God. Those who are fond of music in the theater are fond of it in the house of God when they go thither; and some, professing Christianity, set up such a spurious worship in order to draw people to hear the Gospel! This is doing evil that good may come of it; and by this means, light and trifling people are introduced into the Church of Christ, and when in, are generally very troublesome, hard to be pleased, and difficult to be saved.

And his brother (h) Asaph, who stood on his right hand, [even] Asaph the son of Berachiah, the son of Shimea,
(h) Meaning, the son of Heman, (1-Chronicles 6:33).

And his brother Asaph,.... That is, Heman's brother; so Asaph was, as he was a descendant from the same original ancestor Levi, yet in the line of Gershon; and as being of the same office, a precentor, or chief singer:
who stood on his right hand; he was next to Heman; Heman stood in the middle, which was the most honourable (h), and Asaph on his right hand, and Ethan, after mentioned, on his left; even Asaph, whose name is often met with in the book of Psalm; and his genealogy here stands thus, as traced up to Levi, viz. Berechiah, Shimea, Michael, Baaseiah, Malchiah, Ethni, Zerah, Adaiah, Ethan, Zimmah, Shimei, Jahath, Gershon, Levi.

his brother Asaph--They were brothers naturally, both being descended from Levi, as well as officially, both being of the Levitical order.
