2 Chronicles 29:21-24

21They brought seven bulls, seven rams, seven lambs, and seven male goats 1as a sin offering for the kingdom, the sanctuary, and Judah. And he ordered the priests, the sons of Aaron, to offer them on the altar of the Lord. 22So they slaughtered the bulls, and the priests took the blood and sprinkled it on the altar. They also slaughtered the rams and sprinkled the blood on the altar; they slaughtered the lambs as well, and 2sprinkled the blood on the altar. 23Then they brought the male goats of the sin offering before the king and the assembly, and 3they laid their hands on them. 24The priests slaughtered them and purified the altar with their blood 4to atone for all Israel, because the king ordered the burnt offering and the sin offering for all Israel.
