Ecclesiastes 1:1-2The words of the Preacher, the son of David, king in Jerusalem. Vanity of vanities, saith the Preacher, vanity of vanities; all is vanity.
Ecclesiastes 12:8-10Vanity of vanities, saith the preacher; all is vanity. And 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. The preacher sought to find out acceptable words: and that which was written was upright, even words of truth.
