Deuteronomy 32:40-43

40“Yes, I lift My hand up to heaven and say, ‘As I Myself live forever,

41when I sharpen My lightning sword and My hand seizes it in judgment, I will return vengeance on My foes, and those who hate Me I will pay back.

42I will make My arrows drunk from blood, and My sword will devour flesh— the blood of the slain and the captive, the head of the leaders of the enemy.’

43Make His people rejoice, O nations, for He will avenge the blood of His servants. He will return vengeance on His foes, and atone for the land of His people.”
