So all the service of the LORD was prepared the same day, to keep the Pesach, and to offer burnt offerings on the altar of the LORD, according to the mitzvah of king Yoshiyahu.
The singers the sons of Asaf were in their place, according to the mitzvah of David, and Asaf, and Heman, and Yedutun the king's seer; and the porters were at every gate: they didn't need to depart from their service; for their brothers the Levites prepared for them.
