And their brethren that were in the country came in their weeks as their course came about with them.

And David ordered them on this manner: Zadok of the sons of Eleazar and Ahimelech of the sons of Ithamar to be in office by course.

And David gathered together all the lords of Israel: the lords of the tribes, the lords of the companies that ministered to the king by course, the lords over the thousands and over the hundreds, and the lords over all the goods and cattle of the king and of his sons, with the chamberlains, warriors and all active men unto Jerusalem.

and of the companies of the priests and Levites that waited by course, and of all workmanship, that should serve for the house of the LORD, and for all vessels that should serve in the house of the LORD.
