2 Chronicles 29:20-22

20Early the next morning King Hezekiah gathered the city officials together and went up to the temple of the Lord.

21They brought seven bulls, seven rams, seven male lambs and seven male goats as a sin offering for the kingdom, for the sanctuary and for Judah. The king commanded the priests, the descendants of Aaron, to offer these on the altar of the Lord.

22So they slaughtered the bulls, and the priests took the blood and splashed it against the altar; next they slaughtered the rams and splashed their blood against the altar; then they slaughtered the lambs and splashed their blood against the altar.
