2 Chronicles 29:20

Then they went in to Hezekiah the king within [the palace], and said, "We have cleansed all the house of Yahweh, and the altar of burnt offering, with all its vessels, and the table of show bread, with all its vessels.

Moreover all the vessels, which king Ahaz in his reign did cast away when he trespassed, have we prepared and sanctified; and behold, they are before the altar of Yahweh.

They brought seven bulls, and seven rams, and seven lambs, and seven male goats, for a sin offering for the kingdom and for the sanctuary and for Judah. He commanded the priests the sons of Aaron to offer them on the altar of Yahweh.

So they killed the bulls, and the priests received the blood, and sprinkled it on the altar: and they killed the rams, and sprinkled the blood on the altar: they killed also the lambs, and sprinkled the blood on the altar.
