Thus, through Joel and Amos, we know that at about this time there was an earthquake and a plague of locusts. Historical allusions are rarely made by the prophets, and their predictions bear a general character which does not allow of fixing dates. This incertitude does not exist for Amos, who himself relates that he was denounced by the high priest of Bethel for having predicted the approaching fall of Jeroboam. As he was of Judah, he was requested to go and prophesy in his own country. Since Jehu’s accession, it became known that the declamations of the prophets were not without danger to the dynasties. Prophecy was developed later in Judah than in Israel, perhaps because the priests were more powerful there. A passage in Jeremiah (xxix. 26) tells us that the high priest Jehoiada had established officers in the house of the Lord, who were to put “every man that is mad and maketh himself a prophet,” in prison with chains around their necks. But these restrictive measures could not entirely prevent the development of prophecy, which answered to a public necessity as the press does to-day. Without the opposition maintained among the people by the prophets, the Hebrews would have been a race of slaves, bowing the knee to their masters like other eastern nations. The attachment of the Judeans to the house of David, explains why the part of the prophet was different in the two kingdoms. Instead of stirring up plots like those of Israel, the prophets of Judah attacked the morals of their fellow-citizens. They announced to them that in punishment of their vices, and above all of their impiety, Jehovah would deliver them into the hands of strange conquerors. Their preachings were written, and were addressed to the educated portion of the population. The collections of prophecies in the Bible form one of the most important parts of Hebrew literature, and contain pieces of great beauty. There is a difference of temperament and style among them, but that which is common to all, is an ardent patriotism blending itself with religion. As patriotism is an exclusive sentiment, religion had to bear the same character. It was not sufficient to say that the national god was the most powerful of all gods; it was believed that he was the only God. The prophets did not doubt that after having chastised His people, He would place them at the head of all nations under a new David. The brilliant future they dreamt of corrected the bitterness of their complaints of the present. But the hopes of the Messiah, ever adjourned, were not realised. They were given a mystical meaning, and this change of sense prepared the way for a new religion. [Illustration: JERUSALEM] DESTRUCTION OF THE TWO KINGDOMS [Sidenote: [_ca._ 780-722 B.C.]]
