Currently reading through Proverbs, written by King Solomon, the son of King David - truly a wealth of knowledge!
"Reprove not a scorner, lest he hate thee: rebuke a wise man, and he will love thee. Give instruction to a wise man, and he will be yet wiser: teach a just man, and he will increase in learning. The fear of the LORD is the beginning of wisdom: and the knowledge of the holy is understanding. For by me thy days shall be multiplied, and the years of thy life shall be increased."
