Psalms On Friends Turned Enemies

Yet trusting in G-d alone to avenge himself from evil.

Here’s another proof to bring it to prayers against those who wronged you.

“Despite Betrayal David Prevails”

Listen, O God, to my prayer, do not disregard my pleas.
55:2
May He incite death against them, may they descend to the grave alive, for evil is in their dwelling, within them.
:16
As for me, I shall call unto God, and Hashem will save me.
:17
Evening, morning, and noon, I supplicate and moan; and He has heard my voice.
:18
May God hear and humble them — He Who is enthroned from days of old, Selah — those in whom there is no change! and they fear not God.
:20
Cast upon Hashem your burden and He will sustain you; He will never allow the faltering of the righteous.
:23
… but as for me, I will trust in You.
:24

1 For the conductor, on neginoth, a maskil of David.
2 Incline Your ear, O God, to my prayer and do not disregard my supplication.
3 Hearken to me and answer me; I lament in my speech and I moan,
4 From the voice of the enemy, because of the distress of the wicked; for they accuse me of iniquity and they hate me with a vengeance.
5 My heart shudders within me, and terrors of death have fallen upon me.
6 Fear and trembling come upon me, and horror overcomes me.
7 And I said, “If only I had wings like a dove! I would fly away and be at rest.
8 Behold I would wander far away; I would lodge in the desert forever.
9 I would quickly find myself a refuge from a sweeping wind, from a tempest.”
10 Destroy, O Lord, divide their tongue, for I have seen violence and strife in the city.
11 Day and night they surround it on its walls, and iniquity and sin are in its midst.
12 Destruction is within it, and blows and deceit do not move out of its square.
13 For no enemy reviled me that I should bear it; my enemy did not open his mouth wide against me, that I should hide from him.
14 And you are a man of my equal, my prince and my esteemed one.
15 That together we would devise counsel; in the house of God we would walk with a multitude.
16 May He incite Death upon them; may they descend to the grave alive, for there are evils in their dwelling, in their midst.
17 I shall call to God, and the Lord will save me.
18 Evening, morning, and noontime, I speak and moan, and He hearkened to my voice.
19 He redeemed my soul with peace from the battle that came upon me, because of the many [people who] were with me.
20 May God hear and answer them, and the One who dwells from time immemorial forever, for there is no passing for them, and they did not fear God.
21 He stretched forth his hands against him who was at peace with him; he profaned his covenant.
22 Smooth were the buttery words of his mouth but his heart was set on war; his words were softer than oil, but they are curses.
23 Cast your burden on the Lord, and He will bear you; He shall never allow a righteous man to falter.
24 But You, O God, shall lower them to the Pit of Destruction; men of blood and deceit shall not live half their days, but I will trust in You.
