2 Chronicles 29:3, 16

In the first year of his reign, in the first month, he opened the doors of the house of the Lord [which his father had closed] and repaired them.

The priests went into the inner part of the house of the Lord to cleanse it, and brought out all the uncleanness they found in the temple of the Lord into the court of the Lord's house. And the Levites carried it out to the brook Kidron.
