Deuteronomy 32:41-43

41If 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.

42I 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.’

43Rejoice, O nations, with His people; For He will avenge the blood of His servants, And will render vengeance on His adversaries, And will atone for His land and His people.”
