Proverbs 26:19-21

New Revised Standard Version Catholic Edition

¹⁹ so is one who deceives a neighbor
    and says, “I am only joking!”
²⁰ For lack of wood the fire goes out,
    and where there is no whisperer, quarreling ceases.
²¹ As charcoal is to hot embers and wood to fire,
    so is a quarrelsome person for kindling strife.
