Moses is still singing on the plains of Moab. Verse 4 sits four lines into the Song, immediately after he has called heaven and earth to witness. Before he says one word about Israel's failure, he establishes the fixed point: God is not the problem. The Hebrew audience is about to enter a land where they will fail spectacularly, and Moses is laying down in advance the verse they will need when the exile comes — the verse that says the fault never lay with the Rock.

From the writers we read together

Michael S. Heiser

biblical scholar, author of The Unseen Realm

Heiser reads the Song of Moses as a single, tightly-argued worldview poem. Verses 8-9 set the cosmic geography — the nations to the lesser elohim, Israel to Yahweh. Verse 4 is the prior claim that makes the whole thing coherent. Before Moses can tell Israel that the other gods are inferior, he has to establish that their God is qualitatively different: faithful, just, without iniquity. The contest between Yahweh and the powers is not a contest between bigger and smaller. It is a contest between the Rock and what Heiser elsewhere calls "non-rocks."

This matters today because the powers have not retired; they have rebranded. Every age offers its own bedrock — the market, the nation, the algorithm, the self — and every one of them eventually cracks under weight. Verse 4 is a diagnostic. When something you have trusted gives way, the question is not whether God failed; it is whether you had built on him in the first place. Moses wrote this line for Israel to remember in the ruins. We will need it in ours.
