Ecclesiastes 12:10-13

¹⁰The Preacher sought to find out acceptable words, and that which was written uprightly, even words of truth.

¹¹The words of the wise are as goads; and as nails well fastened are the words of the masters of assemblies, which are given from one shepherd.

¹²And furthermore, my son, be admonished: of making many books there is no end; and much study is a weariness of the flesh.

¹³This is the end of the matter; all hath been heard: Fear God, and keep his commandments; for this is the whole duty of man.
