Ecclesiastes 12:9-12

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.

¹²And moreover, my son, guard thyself by means of them: Of making many books there is no end; And much study is a weariness of the flesh.
