2 Chronicles 29:20-22

20And Hezekiah the king arose early, and gathered the princes of the city, and went up to the house of Jehovah.

21And 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] upon the altar of Jehovah.

22And they slaughtered the bullocks, and the priests received the blood, and sprinkled it on the altar; and they slaughtered the rams, and sprinkled the blood on the altar; and they slaughtered the lambs, and sprinkled the blood on the altar.
