It is difficult to tell which of these fifteen prophets, whose utterances are treasured in this collection, first appeared upon the scene. The probability seems to be that the earliest of them was Joel. Opinions differ widely; I cannot discuss them nor even cite them; but the old theory that Joel lived and preached about eight hundred and seventy-five years before Christ does not seem to me to be invalidated by modern criticism. He was a native of the Southern Kingdom; and at the time we have named, the King of Judea was Joash, whose dramatic elevation to the throne in his seventh year, by Jehoiada the priest, is narrated in the Book of Kings. It was a time of disturbance and disaster in Judah and Jerusalem; the boy-king was but a nominal ruler; the regent was Jehoiada; and incursions of the surrounding tribes, who carried away the people and sold them as slaves, kept the land in a constant state of alarm. Worse than this was the visitation of locusts, continuing, as it would seem, for several years, by which the country was stripped and devastated. This visitation furnishes the theme of the short discourse which is here reported. The description of the march of the locusts over the land is full of poetic beauty; and the people are admonished to accept this as a divine chastisement for their sins, and to do the works meet for repentance. Then comes the promise of the divine forgiveness, and of that great gift of the Spirit, whose fulfillment Peter claimed on the day of Pentecost: "In the midst of the deepest woes which then afflicted the kingdom," says Ewald, "his great soul grasped all the more powerfully the eternal hope of the true community, and impressed it all the more indelibly upon his people, alike by the fiery glow of his clear insight and the entrancing beauty of his passionate utterance." [Footnote: _The History of Israel_, iv. 139.] The next prophet in the order of time is undoubtedly Amos. He tells us that he lived in the days of Uzziah, King of Judah, about seventy years after Joel. He was a herdsman of Tekoa, a small city of Judah, twelve miles south of Jerusalem. In these days the Northern Kingdom was far more prosperous and powerful than the Southern; under Jeroboam II. Israel had become rich and luxurious; and the prophet was summoned, as he declares, by the call of Jehovah himself to leave his herds upon the Judean hills, and betake himself to the Northern Kingdom, there to bear witness against the pride and oppression of its people. This messenger and interpreter of Jehovah to his people is a poor man, a laboring man; but he knows whose commission he bears, and he is not afraid. Stern and terrible are the woes that fall from his lips: the words vibrate yet with the energy of his righteous wrath.
