Ecclesiastes 12:9-14

9Furthermore, Kohelet was not only wise but he also taught the people knowledge. He pondered, sought out, and set in order many proverbs.

10Kohelet searched to find delightful words and truthful, accurate sayings.

11The words of the wise are like goads, their collective sayings are like firmly affixed nails. They have been given by one Shepherd.

12Be warned my son of anything in addition to them: There is no end to the making of many books, and excessive study wearies the flesh.

13A final word, when all has been heard: Fear God and keep His mitzvot! For this applies to all mankind.

14God will bring every deed into judgment, including everything that is hidden, whether it is good or evil.
