That's not exactly what Suetonius said. He's mentioning how the Jewish revolt started, and says:
"There had spread over all the Orient an old and established belief, that it was fated at that time for men coming from Judaea to rule the world. This prediction, referring to the emperor of Rome, as afterwards appeared from the event, the people of Judaea took to themselves; accordingly they revolted and after killing their governor, they routed the consular ruler of Syria as well, when he came to the rescue, and took one of his eagles. Since to put down this rebellion required a considerable army with a leader of no little enterprise, yet one to whom so great power could be entrusted without risk, Vespasian was chosen for the task, both as a man of tried energy and as one in no wise to be feared because of the obscurity of his family and name."
