2 Chronicles 35:15-17

New International Version

¹⁵ The musicians,^(A) the descendants of Asaph, were in the places prescribed by David, Asaph, Heman and Jeduthun the king’s seer. The gatekeepers at each gate did not need to leave their posts, because their fellow Levites made the preparations for them.

¹⁶ So at that time the entire service of the Lord was carried out for the celebration of the Passover and the offering of burnt offerings on the altar of the Lord, as King Josiah had ordered. ¹⁷ The Israelites who were present celebrated the Passover at that time and observed the Festival of Unleavened Bread for seven days.
