Ezekiel 21:13-15

New Catholic Bible

¹³     for the sword has been tested.
And why should it not be so,
    says the Lord God,
    since you have spurned the rod?
¹⁴ As for you, son of man, prophesy,
    and strike your hands together.
Let the sword strike twice,
    even three times.
It is a sword for killing,
    a sword for great slaughter,
    that threatens their enemies on every side.
¹⁵ Therefore, make their hearts melt
    and cause many to fall.
I have posted at the gates
    the sword for slaughter.
The great sword of slaughter
    will flash like lightning.
