evil spirit: The evil spirit was either sent immediately from the Lord, or permitted to come; but whether this was a diabolic possession, or a mere mental malady, is not agreed. It seems to have partaken of both.

His malady appears to have been of a mixed kind, natural and diabolical. There is too much of apparent nature in it to permit us to believe it was all spiritual; and there is too much of apparently supernatural influence, to suffer us to believe it was all natural. 1 Samuel 18:10, 1 Samuel 19:9-10; Judges 9:23; 1 Kings 22:22; Acts 19:15-16
