Thematic Bible: Cleansed by hezekiah

Then they went in to Hezekiah the king within the palace, and said, "We have cleansed all the house of the LORD, and the altar of burnt offering, with all its vessels, and the table of show bread, with all its vessels. Moreover all the vessels, which king Ahaz in his reign threw away when he trespassed, have we prepared and sanctified; and behold, they are before the altar of the LORD." Then Hezekiah the king arose early and gathered the officials of the city and went up to the house of the LORD. read more.
They brought seven bulls, and seven rams, and seven lambs, and seven male goats, for a sin offering for the kingdom and for the sanctuary and for Judah. He commanded the priests the sons of Aaron to offer them on the altar of the LORD. So they killed the bulls, and the priests received the blood, and sprinkled it on the altar: and they killed the rams, and sprinkled the blood on the altar: they killed also the lambs, and sprinkled the blood on the altar. They brought near the male goats for the sin offering before the king and the assembly; and they laid their hands on them: and the priests killed them, and they made a sin offering with their blood on the altar, to make atonement for all Israel; for the king commanded that the burnt offering and the sin offering should be made for all Israel.
