and Mattaniah the son of Mica, the son of Zabdi, the son of Asaph, who was the chief to begin the thanksgiving in prayer, and Bakbukiah, the second among his brothers; and Abda the son of Shammua, the son of Galal, the son of Jeduthun.

For in the days of David and Asaph of old there was a chief of the singers, and songs of praise and thanksgiving to God.
