What does Psalms Chapter 35 say, and which statements belong to its speaker?

The Latin incipit is Dixit injustus. The separate heading concerns sinners' malice and God's goodness; the inscription is unto the end, for God's servant David. The psalm describes an unjust person resolving inwardly to sin, without fear of God before his eyes. He acted deceitfully so iniquity might be found unto hatred; the separate note explains this as hateful to God. Mouth words are iniquity and guile, he would not understand to do well and devised iniquity on his bed, setting himself on ways not good and not hating evil. No time of night or clinical account of self-blinding is given.

The speaker addresses mercy in heaven, truth reaching clouds, justice like God's mountains and judgments a great deep. God will preserve men and beasts. Multiplied mercy leads to children's future trust beneath His wings, inebriation with His house's plenty and drinking of His pleasure's torrent. With Him is life's fountain and in His light they shall see light.

He asks mercy extended to those knowing God and justice to upright hearts, with pride's foot kept away and the sinner's hand not moving him. The last declaration says workers of iniquity are fallen, cast out and could not stand, without identifying a witnessed scene or adding permanently to the wording.
