But some of the more noted prophets endeavoured in a more systematic way to diffuse the spirit which rested upon themselves, and thus to multiply the number of the prophets. They founded schools in which promising young men were gathered and plied with the means of education available in that age, cultivating music, reading the writings of the older prophets, and coming under the influence of the holy man who was at their head. These were the Schools of the Prophets, and their students were the Sons of the Prophets. Samuel seems to have been the first founder of these schools. They were flourishing in the times of Elijah and Elisha, and they probably continued to exist with varying fortunes in subsequent centuries. Perhaps all who went through these schools claimed, or could claim, the prophetic name. Those who took up the profession wore the hairy mantle and leathern girdle made familiar to us by the figure of John the Baptist; and they probably subsisted on the gifts of those who benefited from their oracles. Their numbers may have been very large; we hear of hundreds of prophets even during an idolatrous reign, when they were exposed to persecution. In times when the spirit of inspiration was abroad or when the schools enjoyed the presence of a master spirit, it is easy to understand how valuable such institutions may have been, and how they may have been centres from which religious light and warmth were diffused through the whole country. But they were liable to deterioration. If the general tone of religion in the country declined, they partook in the general decay; an inspiring leader might be taken away and no like-minded successor arise to fill his place; or men who had received no real call beforehand might join the school and pass through the curriculum without receiving it. Only they had learned the trick of speech and got by rote the language of religion. They had no personal knowledge of God or message obtained directly from Him; but it was not difficult to put on the prophet's mantle and talk in the traditional prophetic tones. The fundamental charge against the false prophets is always this: "I have not sent these prophets, yet they ran; I have not spoken unto them, yet they prophesy."
