2 Chronicles 31:3-4; 2 Chronicles 31:21

3 And the king’s part was, that of his proper substance the holocaust should be offered always morning and evening, and on the sabbaths, and the new moons and the other solemnities, as it is written in the law of Moses.

4 He commanded also the people that dwelt in Jerusalem, to give to the priests, and the Levites their portion, that they might attend to the law of the Lord.

21 In all the service of the house of the Lord according to the law and the ceremonies, desiring to seek his God with all his heart, and he did it and prospered.
