2 Chronicles 29:5, 15-19

Then he said to them, “Levites, listen to me! Now consecrate (dedicate) yourselves and consecrate the house of the LORD, the God of your fathers, and get the filth [of idol worship] out of the Holy Place.

They gathered their brothers (fellow Levites) together, consecrated themselves, and went in to cleanse the house of the LORD, as the king had commanded by the words of the LORD. The priests went into the inner part of the house of the LORD to cleanse it, and every unclean thing they found in the temple of the LORD they brought out to the courtyard of the LORD’S house. Then the Levites received it to take out to the Kidron Valley [for disposal]. Now they began the consecration on the first [day] of the first month, and on the eighth day of the month they came to the porch of the LORD. Then for eight days they consecrated the house of the LORD, and on the sixteenth day of the first month they finished. Then they went inside to King Hezekiah and said, “We have cleansed the entire house (temple) of the LORD, the altar of burnt offering with all of its utensils, and the table of showbread with all its utensils. Moreover, we have prepared and consecrated all the utensils which King Ahaz had discarded during his reign in his unfaithfulness; and behold, they are in front of the altar of the LORD.”
