2 Chronicles 29:20-21

¶ Then Hezekiah the king rose early, and gathered the rulers of the city, and went up to the house of the LORD.

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 the LORD.
