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. That Saul had fallen into a deep melancholy, there is little doubt; and that an evil spirit might work more effectually on such a state of mind, there can be little question. 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.
