There's psalm 59:
1: Deliver me from my enemies, O my God, protect me from those who rise up against me,
2: deliver me from those who work evil, and save me from bloodthirsty men.
3: For, lo, they lie in wait for my life; fierce men band themselves against me. For no transgression or sin of mine, O LORD,
4: for no fault of mine, they run and make ready. Rouse thyself, come to my help, and see!
5: Thou, LORD God of hosts, art God of Israel. Awake to punish all the nations; spare none of those who treacherously plot evil. [Selah]
6: Each evening they come back, howling like dogs and prowling about the city.
7: There they are, bellowing with their mouths, and snarling with their lips -- for "Who," they think, "will hear us?"
8: But thou, O LORD, dost laugh at them; thou dost hold all the nations in derision.
9: O my Strength, I will sing praises to thee; for thou, O God, art my fortress.
10: My God in his steadfast love will meet me; my God will let me look in triumph on my enemies.
11: Slay them not, lest my people forget; make them totter by thy power, and bring them down, O Lord, our shield!
12: For the sin of their mouths, the words of their lips, let them be trapped in their pride. For the cursing and lies which they utter,
13: consume them in wrath, consume them till they are no more, that men may know that God rules over Jacob to the ends of the earth. [Selah]
14: Each evening they come back, howling like dogs and prowling about the city.
15: They roam about for food, and growl if they do not get their fill.
16: But I will sing of thy might; I will sing aloud of thy steadfast love in the morning. For thou hast been to me a fortress and a refuge in the day of my distress.
17: O my Strength, I will sing praises to thee, for thou, O God, art my fortress, the God who shows me steadfast love.
Thank you, Knitting, I've printed both of these off to keep near at hand for awhile.
This thread is a Godsend. (ahem) :-)
