Another section which deals with this is Paul at Romans 12: 17 Recompense to no man evil for evil. Provide things honest in the sight of all men. 18 If it be possible, as much as lieth in you, live peaceably with all men. 19 Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord. 20 Therefore if thine enemy hunger, feed him; if he thirst, give him drink: for in so doing thou shalt heap coals of fire on his head. 21 Be not overcome of evil, but overcome evil with good.
Verse 19 is interesting in that it states how God's wrath is to be "given place" by His disciples. In addition v20 teaches that by helping our enemies we will actually "heap coals of fire upon his head." The "imprecatory" (calling down) element of this is in the Christian's anticipation of the wrath and the effects of our actions with the enemies of God. As you allude ours is not to take personal offence but allow for the terrible wrath and vengeance we know of and expect from above. Whatever we pray for is, as all Christians know, in the Hands of God anyway.
Psalm 58:3 The wicked are estranged from the womb: they go astray as soon as they be born, speaking lies. 4 Their poison is like the poison of a serpent: they are like the deaf adder that stoppeth her ear; 5 Which will not hearken to the voice of charmers, charming never so wisely. 6 Break their teeth, O God, in their mouth: break out the great teeth of the young lions, O LORD. 7 Let them melt away as waters which run continually: when he bendeth his bow to shoot his arrows, let them be as cut in pieces. 8 As a snail which melteth, let every one of them pass away: like the untimely birth of a woman, that they may not see the sun."
