2 Chronicles 29:5, 15-19

He said to them, “Listen to me, you Levites! Purify yourselves, and purify the Temple of the LORD, the God of your ancestors. Remove all the defiled things from the sanctuary.

These men called together their fellow Levites, and they all purified themselves. Then they began to cleanse the Temple of the LORD, just as the king had commanded. They were careful to follow all the LORD’s instructions in their work. The priests went into the sanctuary of the Temple of the LORD to cleanse it, and they took out to the Temple courtyard all the defiled things they found. From there the Levites carted it all out to the Kidron Valley. They began the work in early spring, on the first day of the new year, and in eight days they had reached the entry room of the LORD’s Temple. Then they purified the Temple of the LORD itself, which took another eight days. So the entire task was completed in sixteen days. Then the Levites went to King Hezekiah and gave him this report: “We have cleansed the entire Temple of the LORD, the altar of burnt offering with all its utensils, and the table of the Bread of the Presence with all its utensils. We have also recovered all the items discarded by King Ahaz when he was unfaithful and closed the Temple. They are now in front of the altar of the LORD, purified and ready for use.”
