Ecclesiastes 12:12-14

And furthermore, my son, be admonished: of making many books there is no end; and much study is a weariness of the flesh. This is the end of the matter; all hath been heard: Fear God, and keep his commandments; for this is the whole duty of man. For God will bring every work into judgment, with every hidden thing, whether it be good, or whether it be evil.
