Isaiah 66:15-16

New Revised Standard Version Catholic Edition

¹⁵ For the Lord will come in fire,
    and his chariots like the whirlwind,
to pay back his anger in fury,
    and his rebuke in flames of fire.
¹⁶ For by fire will the Lord execute judgment,
    and by his sword, on all flesh;
    and those slain by the Lord shall be many.
