Ecclesiastes 12:8-11

⁸“Vanity of vanities,” says Kohelet. “All is vanity!”

⁹Further, because Kohelet was wise, he still taught the people knowledge. Yes, he pondered, sought out, and set in order many proverbs.

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

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