Ecclesiastes 12:9-12

⁹The Teacher was wise and he taught the people knowledge. He studied and contemplated and set in order many proverbs.

¹⁰The Teacher sought to write using vivid, upright words of truth.

¹¹The words of wise people are like goads. Like nails driven deeply are the words of the masters in collections of their proverbs, which are taught by one shepherd.

¹²My son, be aware of something more: the making of many books, which has no end and much study brings weariness to the body.
