2 Chronicles 29:24-26

Living Bible

²⁴ Then the priests killed the animals and made a sin offering with their blood upon the altar to make atonement for all Israel, as the king had commanded—for the king had specified that the burnt offering and sin offering must be sacrificed for the entire nation.

^25-26 He organized Levites at the Temple into an orchestral group, using cymbals, psalteries, and harps. This was in accordance with the directions of David and the prophets Gad and Nathan, who had received their instructions from the Lord. The priests formed a trumpet corps.
