Solomon’s proverbs were originally short, pithy, easily remembered sayings brought together around certain themes. They started as oral traditions and were eventually written in a Hebrew poetic form known as parallelism. Chapters 10–15 are dominated by antithetical parallelism, meaning a statement is made in line 1 and then contrasted in line 2. Chapters 16–22 contain both synonymous and synthetic parallelism. In synonymous parallelism, the ideas in line 1 are repeated in line 2 using different words. In synthetic parallelism, later lines serve to expand, define, and elaborate the first lines.
