Psalm 78:10

Psalm 78:10, in plain English

They didn't keep their covenant with God; they refused to live by His law. They made a choice not to follow what they had been commanded.

Why it's here

You're seeing the root cause of verse 9's military failure. It wasn't weapons or numbers—it was unfaithfulness. They broke the agreement that bound them to God.

Who's speaking

Asaph, explaining the spiritual failure that led to practical failure.

Where it sits in the story

This is the pattern: covenant unfaithfulness leads to weakness, defeat, exile, suffering. Breaking trust with God breaks everything else.

The scholarly reading

The theological diagnosis underlying military failure: Ephraim did not maintain God's covenant and refused to walk according to His instruction.

Language and setting

The parallelism between breaking covenant (בְרִית, *brit*) and refusing law (תּוֹרָה, *torah*) establishes that military failure is merely the visible symptom of deeper legal-relational rupture. The verb שׁמר (*shamar*, to guard/keep) carries the sense of vigilant preservation of obligation—they neglected this entirely.

Voice

The theological interpreter, explaining the causal logic linking covenant-breach to military defeat.

Significance

Here we see the deuteronomic theology of retribution: national disaster is not random misfortune but the covenantally stipulated consequence of unfaithfulness—what Moses promised in Deuteronomy 28.

8Then they will not be like their fathers, a stubborn and rebellious generation, whose heart was not loyal, whose spirit was not faithful to God.

9The archers of Ephraim turned back on the day of battle.

10They failed to keep God’s covenant and refused to live by His law.

11They forgot what He had done, the wonders He had shown them.

12He worked wonders before their fathers in the land of Egypt, in the region of Zoan.
