Kommentar zu Divrej Hajamim I 16:7

to give thanks to the Lord by the hand of Asaph and his brethren Asaph would commence, “Give thanks to the Lord, call out in His name,” and afterwards all his brethren would respond after him. A similar instance is found in Ezra (Neh. 11:17): “And Mattaniah the son of Micha, the son of Zabdi, the son of Asaph the chief to begin the thanksgiving in prayer,” on the instrument of the huyedoth, as it is written in Ezra (ibid. 12:8): “And the Levites were Jeshua, Binnui, Kadmiel, Sherebiah, Judah, Mattaniah over the huyedoth.”
