KJV

3 He in the first year of his reign, in the first month, opened the doors of the house of the LORD, and repaired them.

15 And they gathered their brethren, and sanctified themselves, and came, according to the commandment of the king, by the words of the LORD, to cleanse the house of the LORD.

16 And the priests went into the inner part of the house of the LORD, to cleanse it, and brought out all the uncleanness that they found in the temple of the LORD into the court of the house of the LORD. And the Levites took it, to carry it out abroad into the brook Kidron.

30 Moreover Hezekiah the king and the princes commanded the Levites to sing praise unto the LORD with the words of David, and of Asaph the seer. And they sang praises with gladness, and they bowed their heads and worshipped.
