¹³ Also for the courses of the priests and the Levites, and for all the work of the service of the house of the Lord, and for all the vessels of service in the house of the Lord.

⁸ So the Levites and all Judah did according to all things that Jehoiada the priest had commanded, and took every man his men that were to come in on the sabbath, with them that were to go out on the sabbath: for Jehoiada the priest dismissed not the courses.

² And Hezekiah appointed the courses of the priests and the Levites after their courses, every man according to his service, the priests and Levites for burnt offerings and for peace offerings, to minister, and to give thanks, and to praise in the gates of the tents of the Lord.

⁴ And 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.

⁵ And 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.

¹⁸ And they set the priests in their divisions, and the Levites in their courses, for the service of God, which is at Jerusalem; as it is written in the book of Moses.
