2 Chronicles 29:10-16

10Now I intend to make a covenant with the LORD, the God of Israel, so that his fierce anger will turn away from us.

11My sons, do not be negligent now, for the LORD has chosen you to stand before him and serve him, to minister before him and to burn incense.”

12Then these Levites set to work: from the Kohathites, Mahath son of Amasai and Joel son of Azariah; from the Merarites, Kish son of Abdi and Azariah son of Jehallelel; from the Gershonites, Joah son of Zimmah and Eden son of Joah;

13from the descendants of Elizaphan, Shimri and Jeiel; from the descendants of Asaph, Zechariah and Mattaniah;

14from the descendants of Heman, Jehiel and Shimei; from the descendants of Jeduthun, Shemaiah and Uzziel. 15When they had assembled their fellow Levites and consecrated themselves, they went in to purify the temple of the LORD, as the king had ordered, following the word of the LORD . 16The priests went into the sanctuary of the LORD to purify it. They brought out to the courtyard of the LORD ’s temple everything unclean that they found in the temple of the LORD . The Levites took it and carried it out to the Kidron Valley.
