Albert Barnes Commentary Deuteronomy 32:43

"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." — Deuteronomy 32:43 (ASV)

Rejoice, O you nations, with His people - Some prefer the marginal rendering.

In this profound passage, there is foreshadowed the purpose of God to overrule:

1. the unbelief of the Jews to the bringing in of the Gentiles; and
2. the mercy shown to the Gentiles to the eventual restoration of the Jews .

The Song closes as it began (Deuteronomy 32:1–3), with an invitation to praise. It has reached, through a long series of divine interpositions, its grandest theme in this call to the Gentiles, now pagan no more, to rejoice over God’s restored people, the Jews.
