Isaiah 66:14-16

New Catholic Bible

¹⁴ When you behold this, your heart will rejoice,
    and your bodies will flourish like grass in spring.
The Lord will make his power known to his servants
    but reveal his wrath to his enemies.
¹⁵ Behold the Lord as he comes in fire,
    his chariots like the whirlwind,
to enact retribution with his furious anger
    and his rebukes with fiery flames.
¹⁶ For the Lord will execute his judgment
    on all mankind with fire and sword,
    and many will be those slain by the Lord.
