In Psalm 35 verses 11-18 David is crying out to God to rescue him, and then gives Him praise.

11 Malicious witnesses rise up;
they ask me of things that I do not know.
12 They repay me evil for good;
my soul is bereft.
13 But I, when they were sick—
I wore sackcloth;
I afflicted myself with fasting;
I prayed with head bowed on my chest.
14 I went about as though I grieved for my friend or my brother;
as one who laments his mother,
I bowed down in mourning.

15 But at my stumbling they rejoiced and gathered;
they gathered together against me;
wretches whom I did not know
tore at me without ceasing;
16 like profane mockers at a feast,
they gnash at me with their teeth.

17 How long, O Lord, will you look on?
Rescue me from their destruction,
my precious life from the lions!
18 I will thank you in the great congregation;
in the mighty throng I will praise you.

Psalm 35:11-18 ESV

Shepherd leader, have faith today. The Good Shepherd is our court of appeals when we are attacked and slandered unjustly. He is our rock, shield, fortress, deliverer, and our refuge. And, He is our hope for tomorrow.
