2 Chronicles 29:4-6 New Revised Standard Version (NRSV)
4 He brought in the priests and the Levites and assembled them in the square on the east. 5 He said to them, “Listen to me, Levites! Sanctify yourselves, and sanctify the house of the Lord, the God of your ancestors, and carry out the filth from the holy place. 6 For our ancestors have been unfaithful and have done what was evil in the sight of the Lord our God; they have forsaken him, and have turned away their faces from the dwelling of the Lord, and turned their backs.
