John Gill Commentary Psalms 59:2

"Deliver me from the workers of iniquity, And save me from the bloodthirsty men." — Psalms 59:2 (ASV)

Deliver me from the workers of iniquity
(See Gill on Psalms 6:8);

and save me from bloody men ;
such as Saul sent to kill David, as appears from the title of the psalm; and such as were concerned in the death of Christ; and such, are the enemies of God's people, the followers of the man of sin. The heap of words, the various expressions used in a way of petition, in this verse and (Psalms 59:1) , show the distress the psalmist was in, and whom he represents; his importunity, earnestness, and fervency in prayer.
