2 Chronicles 29:11-15

My sons, be not now negligent: for the LORD hath chosen you to stand before him, to serve him, and that ye should minister unto him, and burn incense.

Then the Levites arose, Mahath the son of Amasai, and Joel the son of Azariah, of the sons of the Kohathites: and of the sons of Merari, Kish the son of Abdi, and Azariah the son of Jehalelel: and of the Gershonites; Joah the son of Zimmah, and Eden the son of Joah:

And of the sons of Elizaphan; Shimri, and Jeiel: and of the sons of Asaph; Zechariah, and Mattaniah:

And of the sons of Heman; Jehiel, and Shimei: and of the sons of Jeduthun; Shemaiah, and Uzziel.

And they gathered their brethren, and sanctified themselves, and came, according to the commandment of the king, by the words of the LORD, to cleanse the house of the LORD.
