Deuteronomy 32:41-42

Revised Standard Version

⁴¹ if I whet my glittering sword,^[a]
    and my hand takes hold on judgment,
I will take vengeance on my adversaries,
    and will requite 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 heads of the enemy.’
