1. He must tell them of their faults, must show them their rebellions, must show the house of Jacob their sins. Note, Those that are sent to comfort God's people must first convince them, and so prepare them for comfort. Let it suffice you of all your abominations, v. 6. Note, It is time for those that have continued long in sin to reckon it long enough, and too long, and to begin to think of taking up in time, and leaving off their evil courses. "Let the time past of your lives suffice, for by this time, surely, you have surfeited upon your abominations and have become sick of them," 1 Pet. iv. 3. That which is here charged upon them is, (1.) That they had admitted those to the privileges of the sanctuary that were not entitled to them; whereas God had said, The stranger that comes nigh shall be put to death, they had not only connived at the intrusion of strangers into the sanctuary, but had themselves introduced them (v. 7): You brought in strangers uncircumcised in flesh, and therefore under a legal incapacity to enter into the sanctuary, which was a breaking of the covenant of circumcision, throwing down the hedge of their peculiarity, and laying themselves in common with the rest of the world. Yet if these strangers had been devout and good, though they were not circumcised, the crime would not have been so great; but they were uncircumcised in heart too, unhumbled, unreformed, and strangers indeed to God and all goodness. When they came to offer sacrifice they brought these with them to feast with them upon the sacrifice, because they were fond of their company, and this was one of their abominations, wherewith they polluted God's sanctuary; it was giving that which was holy unto dogs, Matt. vii. 6. Note, The admission of those who are openly wicked and profane to special ordinances is a polluting of God's sanctuary and a great provocation to him. (2.) That they had employed those in the service of the sanctuary who were not fit for it. Though none but priests and Levites were to minister in the sanctuary, yet we may suppose that all who were priests and Levites did not immediately attend there, but chosen men of them, who were best qualified, who were most wise, serious, and conscientious, and most likely to keep the charge of the holy things carefully; but, in making this choice, they had not regard to merit and qualification for the work: "You have set keepers of my charge in my sanctuary for yourselves, such as you had some favour or affection for, such as you either had got, or hoped to get, money by, or such as would comply with your humours and would dispense with the laws of the sanctuary to please you; thus you have not kept the charge of my holy things." Note, Those who have the choice of the keepers of the holy things, if, to serve some secular selfish purpose, they choose such as are unfit and unfaithful, will justly have it laid at their door, that they have betrayed the holy things by lodging them in bad hands.
