and Mattaniah the son of Mica, the son of Zabdi, the son of Asaph, who was the leader in beginning the thanksgiving at prayer, and Bakbukiah, the second among his kinsmen; and Abda the son of Shammua, the son of Galal, the son of Jeduthun.

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

Dedication of the Wall

Now at the dedication of the wall of Jerusalem they sought out the Levites from all their places, to bring them to Jerusalem so that they could celebrate the dedication with joy, with songs of thanksgiving and with songs to the accompaniment of cymbals, harps, and lyres.

For in the days of David and Asaph, in ancient times, there were leaders of the singers, songs of praise and songs of thanksgiving to God.
