2 Chronicles 29:17-19

Now they began on the first day of the first month to sanctify, and on the eighth day of the month came they to the porch of Jehovah; and they sanctified the house of Jehovah in eight days: and on the sixteenth day of the first month they made an end. Then they went in to Hezekiah the king within the palace, and said, We have cleansed all the house of Jehovah, and the altar of burnt-offering, with all the vessels thereof, and the table of showbread, with all the vessels thereof. Moreover all the vessels, which king Ahaz in his reign did cast away when he trespassed, have we prepared and sanctified; and, behold, they are before the altar of Jehovah.
