The term prophets in holy writ is of larger extent than to signify only such as foretold things to come; others also who taught the people, pretending authority from God so to do, were called prophets. Thus Bar-jesus, Acts 13:6, is called a false prophet. A false prophet is of the same significance with a false teacher. Against those our Saviour cautions his hearers, as being the most fatal and dangerous enemies to faith and holiness. Some of them indeed come in sheep's clothing, under very fair pretences, and a fair show of religion and strictness; but they are ravening wolves, as dangerous to your souls as ravenous wolves are to a flock of sheep.
