We see that these wise sayings are of Solomon, who is the second son of David and Bathsheba. David and Solomon was each king of Israel for forty years.
The basic meaning of the Hebrew word for proverb is “comparison,” but it came to stand for a wide range of wise pronouncements including the byword lament and thought provoking saying. In the Book of Proverbs the word is used to refer to an aphorism or concise statement of a principle or to a discourse.
The word aphorism (literally "distinction" or "definition", from the Greek: "from-to bound") denotes an original thought, spoken or written in a laconic and easily memorable form.
