2 Chronicles 35:2-6

2He reinstated the kohanim to their duties and encouraged them in the service of the House of Adonai.

3He said to the Levites who taught all Israel and who were consecrated to Adonai, “Put the holy Ark in the House which Solomon the son of King David of Israel built. Since it is no longer a burden on your shoulders now, serve Adonai your God and His people Israel.

4Prepare youselves by your ancestral houses in your divisions, according to the writing of King David of Israel and according to the writing of his son Solomon.

5Stand in the holy place by the divisions of the ancestral houses, by sons of the people and by divisions of ancestral houses of the Levites.

6Now sanctify yourselves, slaughter the Passover lamb and prepare it for your kinsmen, according to the word of Adonai by the hand of Moses.”
