III. That hereby the wickedness of the false prophets themselves shall be manifested to their shame (v. 8): "The watchman of Ephraim was with my God; he had been formerly. They had a set of worthy good ministers, that kept close to God and maintained communion with him; but now they have a race of corrupt, malignant, persecuting prophets, that are the ring-leaders of all mischief." Or, "The watchman of Ephraim now pretends to have been with my God, and prefaces his lies with, Thus saith the Lord; but he is a snare of a fowler in all his ways, and is cunning to draw the simple into sin and the upright into trouble; and he is so full of hatred and enmity to goodness and good men that he has become hatred itself in the house of his God, or against the house of his God." Note, Wicked prophets are the worst of men; their sins against God are most heinous, and their plots against religion most dangerous. They may boast that they are watchmen, speculators, and, as far as speculation goes, they may be right, and with my God, may have their heads full of good notions; but look into their lives, and they are the snare of a fowler in all their ways, catching for themselves and making a prey of others; look into their hearts, and they are hatred in the house of my God, very malicious and spiteful against good ministers and good people. Woe unto thee, O land! unto thee, O church! that hast such watchmen, such prophets, that are seers, but not doers! Corruptio optimi est pessima—The best things, when corrupted, become the worst.
