2 Chronicles 29:21-24

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 the LORD.

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.

23And they brought near the he-goats for the sin offering before the king and the congregation; and they laid their hands upon them:

24and the priests killed them, and they made a sin offering with their blood upon 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.
