39 See now that I, even I, am he, And there is no god with 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 say, As I live for ever, 41 If I whet my glittering sword, And my hand take hold on judgment; I will render vengeance to mine adversaries, And will recompense them that hate me. 42 I will make mine arrows drunk with blood, And my sword shall devour flesh; With the blood of the slain and the captives, From the head of the leaders of the enemy. 43 Rejoice, O ye nations, [with] his people: For he will avenge the blood of his servants, And will render vengeance to his adversaries, And will make expiation for his land, for his people.

Matthew Henry's Commentary on Deuteronomy 32:39-43

Commentary on Deuteronomy 32:39-43

(Read Deuteronomy 32:39-43)

This conclusion of the song speaks, 1. Glory to God. No escape can be made from his power. 2. It speaks terror to his enemies. Terror indeed to those who hate him. The wrath of God is here revealed from heaven against them. 3. It speaks comfort to his own people. The song concludes with words of joy. Whatever judgments are brought upon sinners, it shall go well with the people of God.
