'Choirs' in the Bible

The Levites were Jeshua, Binnui, Kadmiel, Sherebiah, Judah, and Mattaniah who was in charge of the songs of thanksgiving and praise, he and his brothers.

Then I brought up the leaders of Judah to the crest of the wall, and appointed two large thanksgiving choirs, the first of which proceeded on the wall to the right toward the Dung Gate.

Then the two choirs assembled in the Temple of God, as did I, along with half of the officials who accompanied me,

and also Maaseiah, Shemaiah, Eleazar, Uzzi, Jehohanan, Malkijah, Elam, and Ezer. The choirs sang loudly under the direction of Jezrahiah.
