Deuteronomy 32:40-42

Amplified Bible

⁴⁰ 
‘Indeed, I lift up My hand to heaven,
And say (swear an oath), as I live forever,
⁴¹ 
If I sharpen the lightning of My sword,
And My hand takes hold of judgment,
I will render vengeance on My adversaries,
And I will repay those who hate Me.
⁴² 
‘I will make My arrows drunk with blood,
And My sword will devour flesh,
With the blood of the slain and the captives,
From the heads of the leaders of the enemy.’
