Ecclesiastes 12:8-10

ASV(i) 8 Vanity of vanities, saith the Preacher; all is vanity.
9 And further, because the Preacher was wise, he still taught the people knowledge; yea, he pondered, and sought out, [and] set in order many proverbs. 10 The Preacher sought to find out acceptable words, and that which was written uprightly, [even] words of truth.
