1 Samuel 16:21-23

New Revised Standard Version, Anglicised Catholic Edition

²¹ And David came to Saul, and entered his service. Saul loved him greatly, and he became his armour-bearer. ²² Saul sent to Jesse, saying, ‘Let David remain in my service, for he has found favour in my sight.’ ²³ And whenever the evil spirit from God came upon Saul, David took the lyre and played it with his hand, and Saul would be relieved and feel better, and the evil spirit would depart from him.
