"Besides being wise, the Preacher also taught the people knowledge, weighing and studying and arranging proverbs with great care. The Preacher sought to find pleasing words, and uprightly he wrote words of truth. The sayings of the wise are like goads, and like nails firmly fixed are the collected sayings which 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."
-- Ecclesiastes 12:9ff.
