David's Oath of Innocence

Psalms 7:3-5

ADONAI my God, if I have caused this, if there is guilt on my hands,

if I paid back evil to him who was at peace with me, when I even spared those who opposed me without cause;

then let the enemy pursue me until he overtakes me and tramples my life down into the earth; yes, let him lay my honor in the dust. (Selah)
