Proverbs 17:12-14

New Revised Standard Version Catholic Edition

¹² Better to meet a she-bear robbed of its cubs
    than to confront a fool immersed in folly.
¹³ Evil will not depart from the house
    of one who returns evil for good.
¹⁴ The beginning of strife is like letting out water;
    so stop before the quarrel breaks out.
