1 Samuel 16
Saul had been rejected as king over Israel and "the Spirit of the Lord had departed from him". A tormenting spirit was sent by the Lord, filling Saul with depression and fear. Next, the Lord selected one of the son's of Jesse of Bethlehem, David, to be His new King of Israel and asked Samuel to anoint him. "From that day on, the Spirit of the Lord came powerfully upon David".
