2 Chronicles 29:22 (KJV)

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.

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

And the priests killed them, and they made reconciliation with their blood upon the altar, to make an atonement for all Israel: for the king commanded that the burnt offering and the sin offering should be made for all Israel.
