Proverbs 26:19-21

New Revised Standard Version, Anglicised

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