2 Chronicles 35:4
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.
And prepare yourselves,.... To do their work in this service of the sanctuary, the passover; that they be ready to do it, and diligent in it, and perform it according to the law of God:
by the houses of your fathers, after your courses; such of them whose turn in course it was to officiate:
according to the writing of David king of Israel, and according to the writing of Solomon his son; who had given in writing directions in what manner their courses should be observed, see 1 Chronicles 23:1.
