According to the Prayin' Songfacts,this song takes place in jail and finds Strickland Banks being confronted by another inmate who attacks him. The incarcerated singer kills the attacker in self-defence with the help of another prisoner, who in answer to Strickland’s prayers, takes the blame.
Oh Lord above, if I just killed a man
Let somebody take the blame
Oh Lord above, if I'm knelling down
My prayer, take away this pain, oh, nothing helps
