2 Chronicles 29:4-6

4Then he brought in the priests and the Levites, and gathered them in the East Square,

5and 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.

6For our fathers have trespassed and done evil in the eyes of the Lord our God; they have forsaken Him, have turned their faces away from the dwelling place of the Lord, and turned their backs on Him.
