For I will proclaim the name of the LORD; ascribe greatness to our God! The Rock, his work is perfect.
A Song to Outlast Them
At the end of Deuteronomy, God gives Moses a song to teach Israel — not a sermon but a SONG, because a song lodges in the memory and survives generations. Its purpose is sober: God knows Israel will turn away, and the song is planted as a witness that will testify against them and call them back. It opens with the theme that anchors everything: 'The Rock, his work is perfect… a God of faithfulness and without iniquity' (32:4). Against the backdrop of a people who will prove faithless, God is the unchanging Rock — a title the song repeats again and again.
The Nations and the Divine Council
Then comes one of the most discussed verses in the Old Testament. Deuteronomy 32:8-9 says that 'when the Most High gave to the nations their inheritance… he fixed the borders of the peoples' — and here the texts differ. The Masoretic (traditional Hebrew) text reads 'according to the number of the sons of ISRAEL'; the Dead Sea Scrolls and the Septuagint read 'according to the number of the sons of GOD' (i.e., the angelic divine-council beings). Many scholars judge the 'sons of God' reading older. On that reading, at Babel God apportioned the nations to subordinate heavenly powers, while keeping Israel as his own direct portion (32:9). This is the 'divine council' worldview — also seen in Psalm 82 and Daniel 10 — in which spiritual 'princes' stand behind the nations. Theologos flags this as a real textual and interpretive question, lays out both readings, and declares no forced winner; what is undisputed either way is verse 9: 'the LORD's portion is his people.'
The Folly of Idols
The song's center is a lament over idolatry: Israel 'sacrificed to demons that were no gods, to gods they had never known' (32:17 — a verse Paul quotes in 1 Corinthians 10:20 about the reality behind idols). The tragedy is not that the idols are powerful but that they are nothing compared to the Rock who made them — 'they stirred him to jealousy with what is no god.' To trade the living Rock for a carved nothing is the song's picture of sin: not just disobedience but a catastrophic bad trade.
Vengeance and Vindication
The song ends not in abandonment but in vindication. 'Vengeance is mine, and recompense' (32:35 — quoted in Romans 12:19 and Hebrews 10:30): judgment belongs to God, not to his people's grasping hands. And the final note is mercy through judgment — 'Rejoice with him, O heavens… for he will avenge the blood of his servants… and atone for his land and people' (32:43, a verse Hebrews 1:6 applies to the worship of the Son). The faithless people, scattered among the nations apportioned at Babel, will yet be gathered and avenged by the Rock who never moved.
