'Thanksgiving' in the Bible

Mattaniah son of Micah, son of Zabdi, son of Asaph, [who was] the leader to begin the thanksgiving prayer, and Bakbukiah the second of his brothers; Abda son of Shammua, son of Galal, son of Jeduthun.

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

For in the days of David and Asaph from ancient times there was the head of the singers and a song of praise and thanksgiving to God.
