'Priests and Levites' in the Bible

And they did not depart from the command of the king to the priests and Levites concerning any matter, or concerning the treasures.

And Hezekiah set the courses of the priests and the Levites according to their divisions, each 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 Jehovah.
