2 Chronicles 31:2-3

2And Hezekiah appointed the courses of the priests and the Levites after their courses, every man according to his service, both the priests and the Levites, for burnt-offerings and for peace-offerings, to minister, and to give thanks, and to praise in the gates of the camp of Jehovah. 3He appointed also the king’s portion of his substance for the burnt-offerings, to wit, for the morning and evening burnt-offerings, and the burnt-offerings for the sabbaths, and for the new moons, and for the set feasts, as it is written in the law of Jehovah.
