Significance: Peter's diagnosis of Simon Magus — "your heart is not right [he kardia sou ouk estin eutheia] before God" (Acts 8:21) — echoes the language of Ps 78:37's assessment of Israel in the wilderness: "their heart was not steadfast [lo'-nakhon libam] toward Him." Psalm 78 is a historical rehearsal of Israel's pattern of faithless hearts despite God's mighty works — an accusation that fits Simon's situation precisely: he has witnessed the Spirit's powerful works (Acts 8:13-18) yet his desire to purchase the Spirit's gift reveals a heart oriented toward personal power rather than God's glory. The echo positions Simon as recapitulating the wilderness generation's failure to respond rightly to divine manifestation — his "heart not right" is the same covenant unfaithfulness Ps 78:37 condemned in Israel.
