2 Chronicles 29:15 WEB

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  They gathered their brothers, and sanctified themselves, and went in, according to the commandment of the king by the words of Yahweh, to cleanse the house of Yahweh.

¹⁶  The priests went in to the inner part of the house of Yahweh, to cleanse it, and brought out all the uncleanness that they found in the temple of Yahweh into the court of the house of Yahweh. The Levites took it, to carry it out abroad to the brook Kidron.

¹⁷  Now they began on the first [day] of the first month to sanctify, and on the eighth day of the month came they to the porch of Yahweh; and they sanctified the house of Yahweh in eight days: and on the sixteenth day of the first month they made an end.
