2 Chronicles 29:15-19

They assembled their brothers, consecrated themselves, and went in to cleanse the house of the Lord, according to the commandment of the king by the words of the Lord.

So the priests went into the inner part of the house of the Lord to cleanse it, and they brought every unclean thing which they found in the temple of the Lord out to the courtyard of the house of the Lord. Then the Levites received it to carry out to the Kidron Valley.

Now they began the consecration on the first day of the first month, and on the eighth day of the month they entered the porch of the Lord. Then they consecrated the house of the Lord in eight days, and finished on the sixteenth day of the first month.

Then they went in to King Hezekiah and said, “We have cleansed the whole house of the Lord, the altar of burnt offering with all its utensils, and the table of the showbread with all of its utensils.

Moreover, all the utensils which King Ahaz had discarded during his reign in his unfaithfulness, we have prepared and consecrated; and behold, they are before the altar of the Lord.” Hezekiah Restores Temple Worship
