Ecclesiastes 12:11-13

Authorized (King James) Version

¹¹ The words of the wise are as goads, and as nails fastened by the masters of assemblies, which are given from one shepherd. ¹² And further, by these, my son, be admonished: of making many books there is no end; and much study is a weariness of the flesh.

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