2 Chronicles 35:14-15

14After that, the Levites prepared the Passover meal for themselves and for the priests. The priests had been busy all day, until the evening. They were offering the burnt offerings and the pieces of fat to the Lord. So the Levites prepared the meal for themselves and for the priests, Aaron's descendants.

15Asaph's descendants, the musicians, stood in their places. Those were the places that David, Asaph, Heman and the king's prophet, Jeduthun, had chosen. The guards continued to watch the different gates all through the day. So the other Levites prepared the meal for them too.
