2. The presence of a sign; 3. Lastly and chiefly, that the mind of the prophet was given wholly to what was right and good. Although Scripture does not always make mention of a sign, we must nevertheless suppose that a sign was always vouchsafed; for Scripture does not always relate every condition and circumstance (as many have remarked), but rather takes them for granted. We may, however, admit that no sign was needed when the prophecy declared nothing that was not already contained in the law of Moses, because it was confirmed by that law. For instance, Jeremiah's prophecy of the destruction of Jerusalem was confirmed by the prophecies of other prophets, and by the threats in the law, and therefore it needed no sign; whereas Hananiah, who, contrary to all the prophets, foretold the speedy restoration of the state, stood in need of a sign, or he would have been in doubt as to the truth of his prophecy, until it was confirmed by facts. "The prophet which prophesieth of peace, when the word of the prophet shall come to pass, then shall the prophet be known that the Lord hath truly sent him." As, then, the certitude afforded to the prophet by signs was not mathematical (_i.e._, did not necessarily follow from the perception of the thing perceived or seen), but only moral, and as the signs were only given to convince the prophet, it follows that such signs were given according to the opinions and capacity of each prophet, so that a sign which would convince one prophet would fall far short of convincing another who was imbued with different opinions. Therefore the signs varied according to the individual prophet. So also did the revelation vary, as we have stated, according to individual disposition and temperament, and according to the opinions previously held. It varied according to disposition, in this way: if a prophet was cheerful, victories, peace, and events which make men glad, were revealed to him; in that he was naturally more likely to imagine such things. If, on the contrary, he was melancholy, wars, massacres, and calamities were revealed; and so, according as a prophet was merciful, gentle, quick to anger, or severe, he was more fitted for one kind of revelation than another. It varied according to the temper of imagination in this way: if a prophet was cultivated he perceived the mind of God in a cultivated way, if he was confused he perceived it confusedly. And so with revelations perceived through visions. If a prophet was a countryman he saw visions of oxen, cows, and the like; if he was a soldier, he saw generals and armies; if a courtier, a royal throne, and so on.
