Ecclesiastes 12:9-11

9And moreover, because the preacher was wise, he still taught the people knowledge; yea, he gave good heed, and sought out, and set in order many proverbs.1

10The preacher sought to find out acceptable words: and that which was written was upright, even words of truth.2

11The words of the wise are as goads, and as nails fastened by the masters of assemblies, which are given from one shepherd.
