41 When I sharpen my lightning sword and execute judgment, I take vengeance on my enemies and pay back those who hate me. 42 I'll make my arrows drunk with blood, my sword will gorge itself on flesh, Feasting on slain and captive alike, the proud and vain enemy corpses.'" 43 Celebrate, nations, join the praise of his people. He avenges the deaths of his servants, Pays back his enemies with vengeance, and cleanses his land for his people.

Matthew Henry's Commentary on Deuteronomy 32:41-43

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.
