Ecclesiastes 12:9-12

9The Teacher was wise man. He also taught the people to understand things. He studied many proverbs and he wrote them down carefully.

10The Teacher tried to find the right words, so that he could show the true meaning of what he wrote.

11The words of wise people are like sharp sticks that a farmer uses to move his animals along. Their messages are like strong nails in a piece of wood. It is God, our one Shepherd, who gives these messages to us.

12My son, I warn you to be careful about any other teaching. There will always be more and more books to read. If you try to study everything, you will be very weak and tired.
