Matthew, Mark and Luke warn of "false prophets", while Paul made mention of "false apostles" and seems to have been in constant opposition to those who taught a Christ in some way different to the one of whom Paul taught. What is not clear is just what a false apostle was, presumably other than a Christian missionary who disagreed with the particular author.
Matthew 24:11 says, "And many false prophets shall rise, and shall deceive many." Presumably, this acknowledges that Matthew's opponents could indeed prophesy accurately. After all, if enough prophets, false or otherwise, publish prophecies, some of them will come true. Especially if we follow the practice of interpreting prophecies as liberally as possible.
One prophecy that was stated most unambiguously, and yet came true, was made by a man who made no claim that we know of to being a prophet. The Jewish priest and military leader, Josephus, was captured by Vespasian shortly after the appearance in the year 66 of Halley's comet, a "star that stood over Jerusalem". He said that this was an omen that his conqueror, Vespasian, was the Jewish Messiah and would become Emperor of Rome. Vespasian became Roman emperor several years later, just as Josephus had said.
