Ecclesiastes 12:13KJV

11The words of the wise as goads, and as nails fastened the masters of assemblies, are given from one shepherd.

12And further, by these, my son, be admonished: of making many books no end; and much study a weariness of the flesh.

13Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this the whole of man.

14For God shall bring every work into judgment, with every secret thing, whether good, or whether evil.
