Ecclesiastes 12:11

And moreover, because the preacher was wise, he still taught the people knowledge; yea, he gave good heed, and sought out, and set in order many proverbs.

The preacher sought to find out acceptable words: and that which was written was upright, even words of truth.

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.

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