2 Chronicles 29:24-26

Amplified Bible

²⁴ The priests slaughtered them and cleansed the altar from sin with their blood to atone for all Israel, because the king commanded that the burnt offering and the sin offering be made for all Israel.

²⁵ Hezekiah stationed the Levites in the house of the Lord with cymbals, with harps, and with lyres, in accordance with the command of David [his ancestor] and of Gad the king’s seer, and of Nathan the prophet; for the command was from the Lord through His prophets. ²⁶ The Levites stood with the musical instruments of David, and the priests with the trumpets.
