2 Chronicles 29:16

And the priests went into the inner part of the house of the Lord, to cleanse it,.... Into the holy place, where the candlesticks and shewbread tables stood, into which none but priests might enter, but not into the most holy place, the innermost of all; for none but the high priest might go into that, and only on the day of atonement; though in case of necessity, as for repairs, others might go into it, and so perhaps now to cleanse it, if any pollution was there:

and brought out all the uncleanness that they found in the temple of the Lord into the court of the house of the Lord; into the court of the priests, where the Levites might be, and were:

and the Levites took it, to carry it out abroad into the brook Kidron; which ran through the valley of the son of Hinnom, into which all unclean things, and the filth of the temple and sacrifices, were usually carried and cast, see 2 Kings 18:12.
