Isaiah 63:4-6

New Revised Standard Version Catholic Edition

⁴ For the day of vengeance was in my heart,
    and the year for my redeeming work had come.
⁵ I looked, but there was no helper;
    I stared, but there was no one to sustain me;
so my own arm brought me victory,
    and my wrath sustained me.
⁶ I trampled down peoples in my anger,
    I crushed them in my wrath,
    and I poured out their lifeblood on the earth.”
