Samuel probably enacted rules giving a permanent form to the prophetic order; at least in his time the first mention occurs of “schools of the prophets.” These were all near each other, and in Benjamin, namely, in Beth-el, Gilgal, Ramah, and Jericho. Had the prophet been a mere foreteller of events, such schools would have been useless. But he was also God’s representative to ensure the due execution of the Mosaic ritual in its purity; hence arose the need of schools wherein to study that divinely ordained institution. God mostly chose His prophets from those thus educated, though not exclusively, as the cases of Amos (Am 7:14) and Elisha (1 Ki 19:19) prove. The fact that the humblest might be called to the prophetic office acted as a check to the hereditary kingly power and a stimulus to seeking the qualifications needed for so exalted an office. The Messianic Psalms towards the close of this second period form the transition between the prophets of action and the prophets of word, the men who were busy only with the present, and the men who looked out from the present into the glorious future.
