Hebrew writers used a form of poetry that is not dependent on rhyme. Rather, it is noted for its rhythm of thought, or ideas—a literary form called parallelism.” Today I do not need to read Hebrew, because most Bibles are translated into English.
Lines may be synonymous in expression, or they may present contrasting thoughts. For example, various writers of the Psalms are renowned for compressing considerable thought into few words. These writers wrote out of personal experience.
The writings we are scrutinizing used Hebrew poetry while taking different forms. It may rhyme, or it may not. Sometimes it even seems to border on prose. (Ordinary written language)
Beautiful poetry is rarely the work of a shallow mind. Jehovah used ordinary men (Peter, James, and John for instance) but men who were thinkers, men from various professions and backgrounds. Imagine other writers—while being oblivious to the reproach from intellectuals—being labeled: unlettered and ordinary. Not all of them wrote poetic words, but their writings were words organized to have a high, sudden impact.
