Proverbs 14:13-15

Authorized (King James) Version

¹³ Even in laughter the heart is sorrowful;
    and the end of that mirth is heaviness.

¹⁴ The backslider in heart shall be filled with his own ways:
    and a good man shall be satisfied from himself.

¹⁵ The simple believeth every word:
    but the prudent man looketh well to his going.
