2 Chronicles 29:20-22

20Then Hezekiah the king arose early, and gathered the princes of the city, and went up to the house of Jehovah. 21And 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 Jehovah. 22So they killed the bullocks, and the priests received the blood, and sprinkled it on the altar: and they killed the rams, and sprinkled the blood upon the altar: they killed also the lambs, and sprinkled the blood upon the altar.
