2 Chronicles 29:24-26

The priests then slaughtered the goats and presented their blood on the altar for a sin offering to atone for all Israel, because the king had ordered the burnt offering and the sin offering for all Israel. He stationed the Levites in the temple of the LORD with cymbals, harps and lyres in the way prescribed by David and Gad the king’s seer and Nathan the prophet; this was commanded by the LORD through his prophets. So the Levites stood ready with David’s instruments, and the priests with their trumpets.
