Also the Levites which were the singers, all of them of Asaph, of Heman, of Jeduthun, with their sons and their brethren, being arrayed in white linen, having cymbals and psalteries and harps, stood at the east end of the altar, and with them an hundred and twenty priests sounding with trumpets:)

also the Levites who were the singers, all of them, even Asaph, Heman, Jeduthun, and their sons and their brethren, arrayed in fine linen, with cymbals and psalteries and harps, stood at the east end of the altar, and with them a hundred and twenty priests sounding with trumpets;)

Both the Levites and the singing men, that is, both they that were under Asaph, and they that were under Heman, and they that were under Idithun, with their sons, and their brethren, clothed with fine linen, sounded with cymbals, and psalteries, and harps, standing on the east side of the altar, and with them a hundred and twenty priests, sounding with trumpets.

and the Levites the singers, all they of Asaph, of Heman, of Jeduthun, with their sons and their brethren, clad in byssus, with cymbals and lutes and harps, stood at the east end of the altar, and with them a hundred and twenty priests sounding with trumpets),

and the Levites, the singers, to all of them, to Asaph, to Heman, to Jeduthun, and to their sons, and to their brethren, clothed in white linen, with cymbals, and with psalteries, and harps, are standing on the east of the altar, and with them priests, to a hundred and twenty, blowing with trumpets,

And the Levites who made the music, all of them, Asaph, Heman, Jeduthun, and their sons and brothers, robed in fair linen, were in their places with their brass and corded instruments at the east side of the altar, and with them a hundred and twenty priests blowing horns;)

also the Levites who were the singers, all of them, even Asaph, Heman, Jeduthun, and their sons and their brethren, arrayed in fine linen, with cymbals and psalteries and harps, stood at the east end of the altar, and with them a hundred and twenty priests sounding with trumpets-

with both the Levites and the singing men, that is, those who were under Asaph, and those who were under Heman, and those who were under Jeduthun, with their sons and brothers, clothed in fine linen, sounded out with cymbals, and psalteries, and harps, standing toward the eastern side of the altar. And with them were one hundred twenty priests, sounding out with trumpets.

A hundred and twenty priests - Cymbals, psalteries, and harps, of any kind, in union with a hundred and twenty trumpets or horns, could not produce much harmony; as to melody, that must have been impossible, as the noise was too great.

the Levites which were the singers--On great and solemn occasions, such as this, a full choir was required, and their station was taken with scrupulous regard to their official parts: the family of Heman occupied the central place, the family of Asaph stood on his right, and that of Jeduthun on his left; the place allotted to the vocal department was a space between the court of Israel and the altar in the east end of the priests' court.
with them an hundred and twenty priests sounding with trumpets--The trumpet was always used by the priests, and in the divine service it was specially employed in calling the people together during the holy solemnities, and in drawing attention to new and successive parts of the ritual. The number of trumpets used in the divine service could not be less than two (Numbers 10:2), and their greatest number never exceeded the precedent set at the dedication of the temple. The station where the priests were sounding with trumpets was apart from that of the other musicians; for while the Levite singers occupied an orchestra east of the altar, the priests stood at the marble table on the southwest of the altar. There both of them stood with their faces to the altar. The manner of blowing the trumpets was, first, by a long plain blast, then by one with breakings and quaverings, and then by a long plain blast again [BROWN, Jewish Antiquities].

All the Levitic singers and musicians were also engaged in it, to make the festival glorious by song and instrumental music: "and the Levites, the singers, all of them, Asaph, Heman, and Jeduthun, and their sons and brethren, clad in byssus, with cymbals, psalteries, and harps, stood eastward from the altar, and with them priests to 120, blowing trumpets."
