2 Chronicles 29:3, 16

He, in the first year of his reign, in the first month, hath opened the doors of the house of JEHOVAH, and strengtheneth them

and the priests come in to the inner part of the house of JEHOVAH to cleanse [it], and bring out all the uncleanness that they have found in the temple of JEHOVAH to the court of the house of JEHOVAH, and the Levites receive [it], to take [it] out to the brook Kidron without.
