Ecclesiastes 12:9-11

9And moreover, because the Preacher was wise, he still taught the people knowledge; and he pondered, and sought out, [and] set in order many proverbs.

10The Preacher sought to find out acceptable words; and that which was written is upright, words of truth.

11The words of the wise are as goads, and the collections [of them] as nails fastened in: they are given from one shepherd.
