I said in my heart, Come now, I will prove thee with mirth; therefore enjoy pleasure: and, behold, this also was vanity.

Therefore I turned about to cause my heart to despair concerning all the labor wherein I had labored under the sun.

Be not rash with thy mouth, and let not thy heart be hasty to utter anything before God; for God is in heaven, and thou upon earth: therefore let thy words be few.

Because sentence against an evil work is not executed speedily, therefore the heart of the sons of men is fully set in them to do evil.

Therefore remove sorrow from thy heart, and put away evil from thy flesh; for youth and the dawn of life are vanity.
