Proverbs 25:18-23

Revised Standard Version Catholic Edition

¹⁸ A man who bears false witness against his neighbor
    is like a war club, or a sword, or a sharp arrow.
¹⁹ Trust in a faithless man in time of trouble
    is like a bad tooth or a foot that slips.
²⁰ He who sings songs to a heavy heart
    is like one who takes off a garment on a cold day,
    and like vinegar on a wound.^[a]
21 If your enemy is hungry, give him bread to eat;
    and if he is thirsty, give him water to drink;
²² for you will heap coals of fire on his head,
    and the Lord will reward you.
²³ The north wind brings forth rain;
    and a backbiting tongue, angry looks.
