2 Chronicles 29:20-22

20Then Hezekiah the king rose early and gathered the officials of the city and went up to the house of the Lord.

21And they brought seven bulls, seven rams, seven lambs, and seven male 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.

22So they slaughtered the bulls, and the priests received the blood and threw it against the altar. And they slaughtered the rams, and their blood was thrown against the altar. And they slaughtered the lambs, and their blood was thrown against the altar.
