12 Then the Levites arose: Mahath, the son of Amasai and Joel the son of Azariah, from the sons of the Kohathites; and from the sons of Merari, Kish the son of Abdi and Azariah the son of Jehallelel; and from the Gershonites, Joah the son of Zimmah and Eden the son of Joah; 13 and from the sons of Elizaphan, Shimri and Jeiel; and from the sons of Asaph, Zechariah and Mattaniah; 14 and from the sons of Heman, Jehiel and Shimei; and from the sons of Jeduthun, Shemaiah and Uzziel.
15 They assembled their brothers, consecrated themselves, and went in to cleanse the house of the Lord, according to the commandment of the king by the words of the Lord.
16 So the priests went in to the inner part of the house of the Lord to cleanse it, and every unclean thing which they found in the temple of the Lord they brought out to the court of the house of the Lord. Then the Levites received it to carry out to the Kidron valley. 17 Now they began the consecration on the first day of the first month, and on the eighth day of the month they entered the porch of the Lord. Then they consecrated the house of the Lord in eight days, and finished on the sixteenth day of the first month.
18 Then they went in to King Hezekiah and said, “We have cleansed the whole house of the Lord, the altar of burnt offering with all of its utensils, and the table of showbread with all of its utensils. 19 Moreover, all the utensils which King Ahaz had discarded during his reign in his unfaithfulness, we have prepared and consecrated; and behold, they are before the altar of the Lord.”
