II Chronicles 29:1-6

Hezekiah became king when he was twenty-five years old, and he reigned twenty-nine years in Jerusalem. His mother’s name was Abijah the daughter of Zechariah. And he did what was right in the sight of the LORD, according to all that his father David had done. In the first year of his reign, in the first month, he opened the doors of the house of the LORD and repaired them. Then he brought in the priests and the Levites, and gathered them in the East Square, and said to them: “Hear me, Levites! Now sanctify yourselves, sanctify the house of the LORD God of your fathers, and carry out the rubbish from the holy place. For our fathers have trespassed and done evil in the eyes of the LORD our God; they have forsaken Him, have turned their faces away from the dwelling place of the LORD, and turned their backs on Him.
