2 Chronicles 35:2-6

2Josiah also assigned the priests to their duties and encouraged them in their work at the Temple of the Lord.

3He issued this order to the Levites, who were to teach all Israel and who had been set apart to serve the Lord: “Put the holy Ark in the Temple that was built by Solomon son of David, the king of Israel. You no longer need to carry it back and forth on your shoulders. Now spend your time serving the Lord your God and his people Israel.

4Report for duty according to the family divisions of your ancestors, following the directions of King David of Israel and the directions of his son Solomon.

5“Then stand in the sanctuary at the place appointed for your family division and help the families assigned to you as they bring their offerings to the Temple.

6Slaughter the Passover lambs, purify yourselves, and prepare to help those who come. Follow all the directions that the Lord gave through Moses.”
