2 Chronicles 35:2-6

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

3And he said to the Levites, that taught all Israel, [and] who were holy to Jehovah, Put the holy ark in the house that Solomon the son of David, king of Israel, built; ye have not to carry it upon your shoulders. Serve now Jehovah your 1God, and his people Israel;

4and prepare yourselves by your fathers' houses, in your divisions, according to the writing of David king of Israel, and according to the writing of Solomon his son;

5and stand in the sanctuary for the classes of the fathers' houses, for your brethren, the children of the people, and [according] to the divisions of the fathers' houses of the Levites;

6and slaughter the passover, and hallow yourselves, and prepare it for your brethren, that they may do according to the word of Jehovah through Moses.
