2 Chronicles 35:2-6

2And he set the priests in their charges, and encouraged them to the service of the house of Yhwh,

3And said unto the Levites that taught all Israel, which were holy unto Yhwh, Put the holy ark in the house which Solomon the son of David king of Israel did build; it shall not be a burden upon your shoulders: serve now Yhwh your God, and his people Israel,

4And prepare yourselves by the houses of your fathers, after your courses, according to the writing of David king of Israel, and according to the writing of Solomon his son.

5And stand in the holy place according to the divisions of the families of the fathers of your brethren the people, and after the division of the families of the Levites.12

6So kill the passover, and sanctify yourselves, and prepare your brethren, that they may do according to the word of Yhwh by the hand of Moses.
