Deuteronomy 32:33-43

33 their wine is the poison of serpents, and the cruel venom of asps.
34 "Is not this laid up in store with me, sealed up in my treasuries?
35 Vengeance is mine, and recompense, for the time when their foot shall slip; for the day of their calamity is at hand, and their doom comes swiftly.
36 For the LORD will vindicate his people and have compassion on his servants, when he sees that their power is gone, and there is none remaining, bond or free.
37 Then he will say, 'Where are their gods, the rock in which they took refuge,
38 who ate the fat of their sacrifices, and drank the wine of their drink offering? Let them rise up and help you, let them be your protection!
39 "'See now that I, even I, am he, and there is no god beside me; I kill and I make alive; I wound and I heal; and there is none that can deliver out of my hand.
40 For I lift up my hand to heaven, and swear, As I live for ever,
41 if I whet my glittering sword, 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.'
43 "Praise his people, O you nations; for he avenges the blood of his servants, and takes vengeance on his adversaries, and makes expiation for the land of his people."
