2 Chronicles 29:20-24

Then Hezekiah the king arose early, and gathered the princes of the city, and went up to the house of Jehovah. 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 Jehovah. So 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. And they brought near the he-goats for the sin-offering before the king and the assembly; and they laid their hands upon them: and 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.
