When at length the Hebrews, forgetful of their high duties and calling, trampled on their institutions and laws, prophets were raised up to recall the wandering people to their allegiance. ISAIAH, whether he foretells the future destiny of the nation, or the coming of the Messiah, in his majestic eloquence, sweetness, and simplicity, gives us the most perfect model of lyric poetry. He prophesied during the reigns of Azariah and Hezekiah, and his writings bear the mark of true inspiration. JEREMIAH flourished during the darkest period in the history of the kingdom of Judah, and under the last four kings, previous to the Captivity. The Lamentations, in which he pours forth his grief for the fate of his country, are full of touching melancholy and pious resignation, and, in their harmonious and beautiful tone, show his ardent patriotism and his unshaken trust in the God of his fathers. He does not equal Isaiah in the sublimity of his conceptions and the variety of his imagery, but whatever may be the imperfections of his style, they are lost in the passion and vehemence of his poems. DANIEL, after having straggled against the corruptions of Babylon, boldly foretells the decay of that empire with terrible power. His conceptions and images are truly sublime; but his style is less correct and regular than that of his predecessors, his language being a mixture of Hebrew and Chaldaic. Such is also the style of EZEKIEL, who sings the development of the obscure prophesies of his master. His writings abound in dreams and visions, and convey rather the idea of the terrible than of the sublime. These four, from the length of their writings, are called the Greater Prophets, to distinguish them from the twelve Minor Prophets: HOSEA, JOEL, AMOS, OBADIAH, JONAH, MICAH, NAHUM, HABAKKUK, ZEPHANIAH, HAGGAI, ZECHARIAH, and MALACHI, all of whom, though endowed with different characteristics and genius, show in their writings more or less of that fire and vigor which can only be found in writers who were moved and warmed by the very spirit of God. 8. PASTORAL POETRY AND DIDACTIC POETRY.--The Song of Solomon and the history of Ruth are the best specimens of the Hebrew idyl, and breathe all the simplicity of pastoral life. The books of Proverbs and Ecclesiastes contain treatises on moral philosophy, or rather, are didactic poems. The Proverb, which is a maxim of wisdom, greatly used by the ancients before the introduction of dissertation, is, as the name indicates, the prevalent form of the first of these books. In Ecclesiastes we have described the trials of a mind which has lost itself in undefined wishes and in despair, and the efficacious remedies for these mental diseases are shown in the pictures of the vanity of the world and in the final divine judgment, in which the problem of this life will have its complete solution. SOLOMON, the author of these works, adds splendor to the sublimity of his doctrines by the dignity of his style.
