2 Chronicles 29:16-22 NIV

16 The priests went into the sanctuary of the Lord to purify it. They brought out to the courtyard of the Lord’s temple everything unclean that they found in the temple of the Lord. The Levites took it and carried it out to the Kidron Valley.

17 They began the consecration on the first day of the first month, and by the eighth day of the month they reached the portico of the Lord. For eight more days they consecrated the temple of the Lord itself, finishing on the sixteenth day of the first month.

18 Then they went in to King Hezekiah and reported: “We have purified the entire temple of the Lord, the altar of burnt offering with all its utensils, and the table for setting out the consecrated bread, with all its articles.

19 We have prepared and consecrated all the articles that King Ahaz removed in his unfaithfulness while he was king. They are now in front of the Lord’s altar.”

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

21 They 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.

22 So 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.
