2 Chronicles 35:15-17

21st Century King James Version

¹⁵ And the singers, the sons of Asaph, were in their place, according to the commandment of David and Asaph and Heman and Jeduthun the king’s seer. And the doorkeepers waited at every gate; they needed not depart from their service, for their brethren the Levites prepared for them.

¹⁶ So all the service of the Lord was prepared the same day to keep the Passover and to offer burnt offerings upon the altar of the Lord, according to the commandment of King Josiah.

¹⁷ And the children of Israel who were present kept the Passover at that time, and the Feast of Unleavened Bread seven days.
