Ecclesiastes 12:9-12

9In addition to the Teacher being a wise man, he constantly taught the people knowledge; he weighed, explored, and arranged many proverbs.

10The Teacher sought to find delightful sayings and write words of truth accurately.

11The sayings of the wise are like cattle prods, and those from masters of collections are like firmly embedded nails. The sayings are given by one Shepherd.

12But beyond these, my son, be warned: there is no end to the making of many books, and much study wearies the body.
