2 Chronicles 29:3-5

In the first year of his reign, in the first month, he opened the doors of the house of the LORD and repaired them. He brought in the priests and the Levites and assembled them in the square on the east and said to them, “Hear me, Levites! Now consecrate yourselves, and consecrate the house of the LORD, the God of your fathers, and carry out the filth from the Holy Place.
