2 Chronicles 29:20-22

20Then King Hezekiah rose early, gathered the rulers of the city, and went up to the house of the Lord.

21And 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.

22So 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.
