Poetry consists principally in two things—imagery and composition. The composition of poetry differs from that of prose in the manner of mixing long and short syllables together. Take a long syllable out of a line of poetry, and put a short one in the room of it, or put a long syllable where a short one should be, and that line will lose its poetical harmony. It will have an effect upon the line like that of misplacing a note in a song. The imagery in those books called the Prophets appertains altogether to poetry. It is fictitious, and often extravagant, and not admissible in any other kind of writing than poetry. To show that these writings are composed in poetical numbers, I will take ten syllables, as they stand in the book, and make a line of the same number of syllables, (heroic measure) that shall rhyme with the last word. It will then be seen that the composition of those books is poetical measure. The instance I shall first produce is from Isaiah:— “Hear, O ye heavens, and give ear, O earth ’T is God himself that calls attention forth. Another instance I shall quote is from the mournful Jeremiah, to which I shall add two other lines, for the purpose of carrying out the figure, and showing the intention of the poet. “O, that mine head were waters and mine eyes Were fountains flowing like the liquid skies; Then would I give the mighty flood release And weep a deluge for the human race.”—Author.] There is not, throughout the whole book called the Bible, any word that describes to us what we call a poet, nor any word that describes what we call poetry. The case is, that the word prophet, to which a later times have affixed a new idea, was the Bible word for poet, and the word ‘propesying’ meant the art of making poetry. It also meant the art of playing poetry to a tune upon any instrument of music. We read of prophesying with pipes, tabrets, and horns—of prophesying with harps, with psalteries, with cymbals, and with every other instrument of music then in fashion. Were we now to speak of prophesying with a fiddle, or with a pipe and tabor, the expression would have no meaning, or would appear ridiculous, and to some people contemptuous, because we have changed the meaning of the word. We are told of Saul being among the prophets, and also that he prophesied; but we are not told what they prophesied, nor what he prophesied. The case is, there was nothing to tell; for these prophets were a company of musicians and poets, and Saul joined in the concert, and this was called prophesying.
