2 Chronicles 29:19-22

Moreover all the vessels, which king Ahaz in his reign did cast away in his transgression, have we prepared and sanctified, and, behold, they are before the altar of the LORD. Then Hezekiah the king rose early, and gathered the rulers of the city, and went up to the house of the LORD. And they brought seven bullocks, and seven rams, and seven lambs, and seven he goats, for a sin offering for the kingdom, and for the sanctuary, and for Judah. And he commanded the priests the sons of Aaron to offer them on the altar of the LORD. So they killed the bullocks, and the priests received the blood, and sprinkled it on the altar: likewise, when they had killed the rams, they sprinkled the blood upon the altar: they killed also the lambs, and they sprinkled the blood upon the altar.
