2nd Chronicles 29:17

14 and of the sons of Heman: Jehiel and Shimei; and of the sons of Jeduthun: Shemaiah and Uzziel --

15 and they gather their brethren, and sanctify themselves, and come in, according to the command of the king in the matters of Jehovah, to cleanse the house of Jehovah,

16 and the priests come in to the inner part of the house of Jehovah to cleanse [it], and bring out all the uncleanness that they have found in the temple of Jehovah to the court of the house of Jehovah, and the Levites receive [it], to take [it] out to the brook Kidron without.

17 And they begin on the first of the first month to sanctify, and on the eighth day of the month they have come to the porch of Jehovah, and they sanctify the house of Jehovah in eight days, and on the sixteenth day of the first month they have finished.

18 And they come in within unto Hezekiah the king, and say, `We have cleansed all the house of Jehovah, and the altar of the burnt-offering, and all its vessels, and the table of the arrangement, and all its vessels,

19 and all the vessels that king Ahaz cast away in his reign -- in his trespass -- we have prepared and sanctified, and lo, they [are] before the altar of Jehovah.`

20 And Hezekiah the king riseth early, and gathereth the heads of the city, and goeth up to the house of Jehovah;
