What does Psalms Chapter 108 say, and which statements belong to its speaker?

Deus, laudem meam is the incipit; the heading interprets David speaking as Christ against persecutors, especially Judas, approving foreseen punishment for obstinacy and final impenitence. The inscription is unto the end for David. The speaker asks no silence in praise while wicked and deceitful mouths open, deceitful tongues and hatred surround and attack without cause. He gave himself to prayer amid detraction repaying love and evil repaying good.

He asks sinner set over an adversary and devil at right hand. The note interprets the devil as arch-sinner possessing him and links imprecations in thirty verses to thirty silver pieces, calling them prophetic denunciations concerning traitor and accomplices described as Jews, not properly curses. That historical edition interpretation remains attributed, not a claim about present people. Requests ask condemnation, prayer turned to sin, few days, another taking bishopric, fatherless children, widowed wife, wandering begging children expelled from homes, usurer searching substance and strangers plundering labor, no helper or pity for offspring, posterity cut and name erased in one generation. Fathers' iniquity and mother's sin are requested remembered continually, memory perishing, because he failed mercy and persecuted poor, beggar and broken-hearted to death. None of these requested household events is presented as a witnessed Judas family history; Acts, Peter and Matthias are not added.

He loved cursing, which shall come, refused blessing, which shall stay far, put cursing on like garment, entering entrails like water and bones like oil. He asks it as covering garment and continual girdle, calling this detractors' work. He asks delivery for sweet mercy and name, describing poor needy troubled heart, declining-shadow removal and locust-like shaking, knees weakened by fasting and flesh changed for oil. The note explains emaciation and lost fatness. People saw, reproached and shook heads.

He asks help, mercy's saving and recognition of God's hand. They will curse and God bless; he asks risers confounded and detractors clothed in shame like double cloak, while servant shall rejoice. He will thank with mouth and praise among many because God has stood at poor person's right hand to save his soul from persecutors. Future praise and requested shame are distinct from remembered help, without an achieved triumphant resolution.
