2 Chronicles 35:15-16

15The singers (Asaph’s descendants) were in their places as David, Asaph, Heman, and the king’s seer  Jeduthun had commanded. The gatekeepers were stationed at each gate. They didn’t need to leave their work, because their relatives, the Levites, prepared ⌞animals⌟ for them.

16So everything was arranged that day for the worship of the Lord. The Passover was celebrated, and the burnt offerings were sacrificed on the Lord’s altar as King Josiah had commanded.
