2nd Chronicles 29:12

9 For see, our fathers have been put to death with the sword, and our sons and daughters and wives have been taken away prisoners because of this.

10 Now it is my purpose to make an agreement with the Lord, the God of Israel, so that the heat of his wrath may be turned away from us.

11 My sons, take care now: for you have been marked out by the Lord to come before him and to be his servants, burning offerings to him.

12 Then the Levites took their places; Mahath, the son of Amasai, and Joel, the son of Azariah, among the Kohathites; and of the sons of Merari, Kish, the son of Abdi, and Azariah, the son of Jehallelel; and of the Gershonites, Joah, the son of Zimmah, and Eden, the son of Joah;

13 And of the sons of Elizaphan, Shimri and Jeuel; and of the sons of Asaph, Zechariah and Mattaniah;

14 And of the sons of Heman, Jehuel and Shimei; and of the sons of Jeduthun, Shemaiah and Uzziel.

15 And they got their brothers together and made themselves holy, and went in, as the king had said by the word of the Lord, to make the house of the Lord clean.
