Ecclesiastes 12:8-11

⁸Vanity of vanities, said the Preacher; all is vanity.

⁹And because the Preacher was wise above others, so it was that he taught man excellent knowledge, and the ear will trace out the parables.

¹⁰The Preacher sought diligently to find out acceptable words, and a correct writing, even words of truth.

¹¹The words of the wise are as goads, and as nails firmly fastened, which have been given from one shepherd by agreement.
