Sirach 28:8-10

New Revised Standard Version, Anglicised

⁸ Refrain from strife, and your sins will be fewer;
    for the hot-tempered kindle strife,
⁹ and the sinner disrupts friendships
    and sows discord among those who are at peace.
¹⁰ In proportion to the fuel, so will the fire burn,
    and in proportion to the obstinacy, so will strife increase;^[a]
in proportion to a person’s strength will be his anger,
    and in proportion to his wealth he will increase his wrath.
