A wise man will hear and increase learning and a man of understanding will attain free counsel. Proverbs 1:5
The principal author of Proverbs as King Solomon who was one of the wisest men who ever lived and one of the richest too.
Solomon collected as well as wrote the proverbs. In I Kings 4:32 we read that he spoke 3,000 proverbs. In Ecclesiastes 1:1 he called himself “the preacher.” As such, he no doubt collected and quoted useful expressions just as a modern preacher might quote a poem or other saying.
