Wisdom of Ben Sira 28:9-11

New Catholic Bible

⁹ A sinner disrupts friendships
    and sows discord among those who are peacefully disposed.
¹⁰ The more fuel there is, the fiercer the fire will burn;
    the greater the obstinacy shown, the fiercer will be the strife.
The greater is the power of a man, the greater will be his anger;
    the greater his wealth, the greater his wrath will be.
¹¹ A sudden quarrel kindles a fire,
    and a hasty dispute leads to bloodshed.
