2 Chronicles 35:15-17

Revised Standard Version

¹⁵ The singers, the sons of Asaph, were in their place according to the command of David, and Asaph, and Heman, and Jedu′thun the king’s seer; and the gatekeepers were at each gate; they did not need to depart from their service, for their brethren the Levites prepared for them.

¹⁶ So all the service of the Lord was prepared that day, to keep the passover and to offer burnt offerings on the altar of the Lord, according to the command of King Josi′ah. ¹⁷ And the people of Israel who were present kept the passover at that time, and the feast of unleavened bread seven days.
