God Marches from Sinai and Provides for His People
The poem remembers God going before his people through the wilderness, with earth and heavens reacting to his presence. Sinai, rain, inheritance, and provision combine exodus imagery with divine kingship.
This retrospective movement matters for understanding verse 18: Psalm 68’s ascent language grows out of a larger divine-warrior story rather than appearing as an isolated prediction. Free therefore builds the historical and literary context before reaching Paul’s Christological use.
