2 Chronicles 29:3-5 NIV
In the first month of the first year of his reign, he opened the doors of the temple of the LORD and repaired them. He brought in the priests and the Levites, assembled them in the square on the east side and said: “Listen to me, Levites! Consecrate yourselves now and consecrate the temple of the LORD, the God of your ancestors. Remove all defilement from the sanctuary.
