Besides being wise, the Preacher also taught the people knowledge, weighing and studying and arranging many proverbs with great care. The Preacher sought to find words of delight, and uprightly he wrote words of truth.
The words of the wise are like goads, and like nails firmly fixed are the collected sayings. They are given by one Shepherd. My son, beware of anything beyond these. Of making many books there is no end, and much study is a weariness of the flesh.
The end of the matter. All has been heard. Fear God and keep His commandments, for this is the whole duty of man. For God will bring every deed into judgment, with every secret thing, whether good or evil. (Ecclesiastes 12.9-14)
