What does Psalms Chapter 65 say, and which statements belong to its speaker?

The Latin incipit is Jubilate Deo. The heading invites praise; the inscription is unto the end, a canticle of resurrection. Earth is called to shout, sing and glorify God's name and terrible works. In His strength enemies shall lie to Him, not simply cringe. Earth is invited to adore and behold counsels over humanity. He turns sea to dry land; in the river they shall pass on foot and there the speakers shall rejoice. He rules forever and beholds nations; provokers are warned against self-exaltation.

Gentiles are called to bless God, who set the speaker's soul to live and did not allow feet moved. The speakers recall proving by fire like silver, a net, back's afflictions, men set over heads and passage through fire and water into refreshment. No named arrogant ruler or furnace event is independently identified.

The speaker will enter God's house with burnt offerings and pay vows uttered in trouble. He will offer marrow-filled holocausts, rams, bullocks and goats; these are promised offerings rather than completed altar actions. He invites fearers to hear what God did for his soul, recalls crying and extolling, states conditionally that if he looked at iniquity in heart the Lord will not hear, then says God heard supplication. He blesses God who did not turn away prayer or mercy. The speaker's argument is not turned into a universal causal guarantee for perfectly pure people's prayers.
