What does Psalms Chapter 7 say, and which statements belong to its speaker?

The Latin incipit is Domine, Deus meus. The separate heading identifies David's trust in his cause's justice and prayer against enemies. The inscription says he sang to the Lord for the words of Chusi, son of Jemini. David puts trust in God and asks deliverance from persecutors, lest his soul be seized like a lion with no redeemer or savior.

In the psalmist’s speech, he says conditionally that if he did this thing, has iniquity in his hands or rendered to those repaying evil, let him fall empty before enemies. Let the enemy pursue and take his soul, tread his life to earth and bring glory to dust. He asks the Lord to arise in anger, be exalted in enemies' borders and arise in His commanded precept. A congregation will surround Him, and David asks Him to return on high for their sake.

In the psalmist’s speech, david asks judgment according to his justice and innocence. He says sinners' wickedness will be brought to nothing, God directs the just and searches hearts and reins, and help comes from the Lord who saves the upright. He calls God just, strong and patient and asks whether He is angry every day. Unless they convert, He will brandish a sword and has readied bow and instruments of death, with arrows for those who burn. The separate note identifies those who burn as persecutors of saints, not the arrows as flaming.

In the psalmist’s speech, the psalm describes labor with injustice, conceived sorrow and born iniquity, a dug pit into which its maker falls, and sorrow and iniquity returning on his head and crown. David vows glory and song to the Lord Most High; the passage supplies no particular accusation by Chusi or documented ensuing capture.
