2 Chronicles 35:1-4

Josiah observed the Lord’s Passover  and slaughtered the Passover lambs on the fourteenth day of the first month.  He appointed the priests to their responsibilities and encouraged them to serve in the Lord’s temple.  He said to the Levites who taught all Israel  the holy things of the Lord, “Put the holy ark in the temple built by Solomon son of David king of Israel. Since you do not have to carry it on your shoulders,  now serve the Lord your God and his people Israel. “Organize your ancestral families  by your divisions  according to the written instruction of King David of Israel and that of his son Solomon.
