Ecclesiastes 12:8-14

[8] Vanity of vanities, says the Preacher; all is vanity.
[9] Besides being wise, the Preacher also taught the people knowledge, weighing and studying and arranging proverbs with great care.
[10] The Preacher sought to find pleasing words, and uprightly he wrote words of truth.
[11]The sayings of the wise are like goads, and like nails firmly fixed are the collected sayings which are given by one Shepherd.
[12] My son, beware of anything beyond these. Of making many books there is no end, and much study is a weariness of the flesh.
[13] The end of the matter; all has been heard. Fear God, and keep his commandments; for this is the whole duty of man.
[14] For God will bring every deed into judgment, with every secret thing, whether good or evil.
