2 Chronicles 29:3-5

Hezekiah opened the doors of the Temple of the LORD and repaired them in the first month of the first year he was king. Hezekiah brought in the priests and Levites and gathered them in the courtyard on the east side of the Temple. Hezekiah said, “Listen to me, Levites. Make yourselves ready for the LORD’s service, and make holy the Temple of the LORD, the God of your ancestors. Remove from the Temple everything that makes it impure.
