These features of Hebrew poetry, however, spring from its internal force rather than from any external form. Indeed, the Hebrew poets soar far above all others in that energy of feeling, impetuous and irresistible, which penetrates, warms, and moves the very soul. They reveal their anxieties as well as their hopes; they paint with truth and love the actual condition of the human race, with its sorrows and consolations, its hopes and fears, its love and hate. They select their images from the habitual ideas of the people, and personify inanimate objects--the mountains tremble and exult, deep cries unto deep. Another characteristic of Hebrew poetry is the strong feeling of nationality it expresses. Of their two most sublime poets, one was their legislator, the other their greatest king. 7. LYRIC POETRY.--In their national festivals the Hebrews sang the hymns of their lyric poets, accompanied by musical instruments. The art of singing, as connected with poetry, flourished especially under David, who instituted twenty-four choruses, composed of four thousand Levites, whose duty it was to sing in the public solemnities. It is generally believed that the Hebrew lyric poetry was not ruled by any measure, either of syllables or of time. Its predominant form was a succession of thoughts and a rhythmic movement, less of syllables and words than of ideas and images systematically arranged. The Psalms, especially, are essentially symmetrical, according to the Hebrew ritual, their verses being sung alternately by Levites and people, both in the synagogues and more frequently in the open air. The song of Moses after the passage of the Bed Sea is the most sublime triumphal hymn in any language, and of equal merit is his song of thanksgiving in Deuteronomy. Beautiful examples of the same order of poetry may be found in the song of Judith (though not canonical), and the songs of Deborah and Balaam. But Hebrew poetry attained its meridian splendor in the Psalms of David. The works of God in the creation of the world, and in the government of men; the illustrious deeds of the House of Jacob; the wonders and mysteries of the new Covenant are sung by David in a fervent out-pouring of an impulsive, passionate spirit, that alternately laments and exults, bows in contrition, or soars to the sublimest heights of devotion. The Psalms, even now, reduced to prose, after three thousand years, present the best and most sublime collection of lyrical poems, unequaled for their aspiration, their living imagery, their grand ideas, and majesty of style.
