2 Chronicles 29:1-5

Hezekiah became king when he was twenty-five years old; and he reigned twenty-nine years in Jerusalem. And his mother’s name was Abijah, the daughter of Zechariah. He did 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. He brought in the priests and the Levites and gathered them into the square on the east. Then he said to them, “Listen to me, O Levites. Consecrate yourselves now, and consecrate the house of the LORD, the God of your fathers, and carry the uncleanness out from the holy place.
