II Chronicles 29:20-24

Then King Hezekiah rose early, gathered the rulers of the city, and went up to the house of the LORD. And they brought seven bulls, seven rams, seven lambs, and seven male goats for a sin offering for the kingdom, for the sanctuary, and for Judah. Then he commanded the priests, the sons of Aaron, to offer them on the altar of the LORD. So they killed the bulls, and the priests received the blood and sprinkled it on the altar. Likewise they killed the rams and sprinkled the blood on the altar. They also killed the lambs and sprinkled the blood on the altar. Then they brought out the male goats for the sin offering before the king and the assembly, and they laid their hands on them. And the priests killed them; and they presented their blood on the altar as a sin offering to make an atonement for all Israel, for the king commanded that the burnt offering and the sin offering be made for all Israel.
