If you chain the curses to the lectern then the Psalmist is focused on applying confession with great care. But if you allow the scripture to speak for itself the Psalmist is complains about His sin and coming for deliverance by cursing his enemies.


When I was a monk, I made a great effort to live according to the requirements of
the monastic rule. I made a practice of confessing and reciting all my sins, but always with prior contrition; I went to confession frequently, and I performed the assigned penances faithfully. Nevertheless, my conscience could never achieve certainty but was always in doubt and said: “You have not done this correctly. You were not contrite enough. You omitted this in your confession.” Therefore, the longer I tried to heal my uncertain, weak, and troubled conscience with human traditions, the more uncertain, weak, and troubled I continually made it. In this way, by observing human traditions, I transgressed them even more; and by following the righteousness of the monastic order, I was never able to reach it.
