Psalms 35:11-16

Malicious witnesses rise up; They ask me of things that I do not know. They repay me evil for good, To the sorrow of my soul. But as for me, when they were sick, my clothing was sackcloth (mourning garment); I humbled my soul with fasting, And I prayed with my head bowed on my chest. I behaved as if grieving for my friend or my brother; I bowed down in mourning, as one who sorrows for his mother. But in my stumbling they rejoiced and gathered together [against me]; The slanderers whom I did not know gathered against me; They slandered and reviled me without ceasing. Like godless jesters at a feast, They gnashed at me with their teeth [in malice].
