Proverbs 17:12-14

Revised Standard Version Catholic Edition

¹² Let a man meet a she-bear robbed of her cubs,
    rather than a fool in his folly.
¹³ If a man returns evil for good,
    evil will not depart from his house.
¹⁴ The beginning of strife is like letting out water;
    so quit before the quarrel breaks out.
