2 Chronicles 29:3-5

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