What does Psalms Chapter 68 say, and which statements belong to its speaker?

The Latin incipit is Salvum me fac, Deus. The separate heading interprets Christ's passion and persecutors' reprobation. David's inscription names those to be changed; the note interprets converts remembering the passion. The speaker asks saving from soul-reaching waters and recalls mire without footing, tempest, hoarse crying and failing eyes while hoping. The note identifies waters as afflictions, citing sorrow unto death. He describes causeless haters more numerous than head's hairs and payment of what he did not take. A separate note applies restitution to Christ's punishment for human sins. His foolishness and offences are known; the note offers enemies' imputations or human sins taken upon himself.

He asks seekers not shamed on his account, describes borne reproach, estrangement from brethren and mother's sons, zeal for God's house and its reproaches falling on him. Fasting and haircloth became reproach and byword; gate sitters spoke against him and wine drinkers made him a song. No tears or assigned civic offices are added. He prays for the time of good pleasure, mercy and salvation, asking extraction from mire, haters and deep waters, no drowning or pit's closure, kind mercy, an unaverted face and speedy soul delivery.

God knows reproach and shame. He expected misery and found neither grieving companion nor comforter. They gave gall for food and vinegar in thirst. He asks table become snare, recompense and stumblingblock. The separate note interprets subsequent imprecations as prophecy of Jews' punishment for obstinacy; it is not new universal doctrine about suffering. Requests continue for darkened eyes, bent backs, indignation, desolate dwellings, added iniquity, exclusion from justice and blotting from living's book because persecutors added to the wounds of one God smote.

Poor and sorrowful, he says salvation set him up. He will praise with a canticle, which shall please better than a young calf with horns and hoofs. Poor people are called to joy and seeking God for soul's life; God heard poor and did not despise prisoners. Heavens, earth, sea and creeping things are called to praise. God will save Sion and build Juda's cities for inheritance and servants' seed, with lovers dwelling. The separate note interprets church and worldwide worship places. Comparative praise is not abolition of all offerings or a causal guarantee of restoration.
