Ecclesiastes 12:9-12

9Besides being wise, the spokesman also taught the people what he knew. He very carefully thought about it, studied it, and arranged it in many proverbs.

10The spokesman tried to find just the right words. He wrote the words of truth very carefully.

11Words from wise people are like spurs. Their collected sayings are like nails that have been driven in firmly. They come from one shepherd.

12Be warned, my children, against anything more than these. People never stop writing books. Too much studying will wear out your body.
