2 Chronicles 29:3-5

American Standard Version

³ He in the first year of his reign, in the first month, opened the doors of the house of Jehovah, and repaired them. ⁴ And he brought in the priests and the Levites, and gathered them together into the broad place on the east, ⁵ and said unto them, Hear me, ye Levites; now sanctify yourselves, and sanctify the house of Jehovah, the God of your fathers, and carry forth the filthiness out of the holy place.
