Ezekiel 44:8

And ye have not kept the charge of Mine holy things, in treating the appointments of the Temple without the reverence which He demands; but ye have set keepers of My charge in My Sanctuary for yourselves, literally, "but ye appoint for keepers of My charge in My Sanctuary those," that is, such people, such men, as their representatives in performing the functions of their religious cult. Their worship, therefore, was not a service of God, but a service of their own inclination and thus altogether sinful. In condemnation of such practices the Lord now gives some definite rules concerning the service in His new Temple.
