Deuteronomy 32:40-42 New Revised Standard Version Catholic Edition (NRSVCE)
40 For I lift up my hand to heaven,
and swear: As I live forever,
41 when I whet my flashing sword,
and my hand takes hold on judgment;
I will take vengeance on my adversaries,
and will repay those who hate me.
42 I will make my arrows drunk with blood,
and my sword shall devour flesh—
with the blood of the slain and the captives,
from the long-haired enemy.
