II 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. Then he brought in the priests and the Levites, and gathered them in the East Square, and said to them: “Hear me, Levites! Now sanctify yourselves, sanctify the house of the LORD God of your fathers, and carry out the rubbish from the holy place.
