So I did my homework, and the answer is:
Ps. 58 ("The upright will bathe his feet in the blood of the wicked.")Taken as a whole, none of those Psalms is especially violent or offensive. And Ps. 109 (against enemies) has some magnificent lines: "Let them curse, provided that You bless.... I shall praise God before all people, for he stands at the side of the poor.")
Ps. 83 ("Treat them like Midian...to manure the ground.")
Ps. 109 ("May God never forget the crimes of his ancestors... may no one take pity on his orphans."
I understand that in the monasteries, they continue praying the Psalms--all 150 o f them.
We may yet need those cursing Psalms ourselves.
