Ecclesiastes 12:8-10

Leeser(i) 8 Vanity of vanities, saith Koheleth: all is vanity.— 9 And in addition to this that Koheleth was wise, he continually also taught the people knowledge, and he probed, and searched out, and composed many proverbs. 10 Koheleth sought to find out acceptable words, and that which would be written down uprightly, even words of truth.
