Ecclesiastes 7:20-24

For there is not a just man upon earth, that doeth good, and sinneth not.

Also take no heed unto all words that are spoken; lest thou hear thy servant curse thee:

For oftentimes also thine own heart knoweth that thou thyself likewise hast cursed others.

All this have I proved by wisdom: I said, I will be wise; but it was far from me.

That which is far off, and exceeding deep, who can find it out?
