2 Chronicles 29:17-19

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.”
