Ecclesiastes 12:11-14

Words from wise people are like sharp sticks used to guide animals. They are like nails that have been driven in firmly. Altogether they are wise teachings that come from one Shepherd. So be careful, my son, about other teachings. People are always writing books, and too much study will make you tired. Now, everything has been heard, so I give my final advice: Honor God and obey his commands, because this is all people must do. God will judge everything, even what is done in secret, the good and the evil.
