David's music drives away Saul's harmful spirit — a type of exorcism

1 Sam 16:23: whenever the harmful spirit came upon Saul, David played the lyre and Saul was refreshed and the spirit departed. Mike argues this is significant because David was not playing just any music but divinely inspired, anointed worship songs. He references the Qumran texts which associated some Davidic psalms with exorcism, particularly Psalm 91 with its language of treading on serpents as a possible spiritual-warfare connotation. This gives credence to reading the Saul episode as an OT exorcism.
