Ecclesiastes 12:10-12

Revised Standard Version

¹⁰ The Preacher sought to find pleasing words, and uprightly he wrote words of truth.

¹¹ The sayings of the wise are like goads, and like nails firmly fixed are the collected sayings which are given by one Shepherd. ¹² My son, beware of anything beyond these. Of making many books there is no end, and much study is a weariness of the flesh.
