The thief cometh not but for to steal,.... That is his first and principal view; to steal, is to invade, seize, and carry away another's property. Such teachers that come not in by the right door, or with a divine commission, seek to deceive, and carry away the sheep of Christ from him, though they are not able to do it; and to steal away their hearts from him, as Absalom stole the hearts of the people from their rightful lord and sovereign, David his father; and to subject them to themselves, that they might lord it over them, and make a property of them, as the Pharisees did, who, under a pretence of long prayers, devoured widows' houses.
And to kill and to destroy; either the souls of men by their false doctrines, which eat as doth a cancer, and poison the minds of men, and slay the souls that should not die, subverting the faith of nominal professors, though they cannot destroy any of the true sheep of Christ; or the bodies of the saints, by their oppression, tyranny, and persecution, who are killed all the day long for the sake of Christ, and are accounted as sheep for the slaughter, by these men, they thinking that by so doing they do God good service.
