1 Samuel 16:14

“But the Spirit of the Lord departed from Saul, etc.] As a spirit of prophecy as at first, as a spirit of wisdom and prudence in civil government, and as a spirit of fortitude and courage, as the Targum: and an evil spirit from the Lord troubled him; the reverse of the former, which by the permission of God, and as a punishment to him for his sins, came upon him; he seemed to be a demoniac, as Josephus represents f327 him, as if possessed with the devil; by whom he was almost suffocated and strangled, as well as was distracted in his counsels, and became weak and foolish; lost all courage and greatness of mind, was timorous and fearful, and alarmed by everything, and was full of envy,…”

“The Spirit of the Lord departed from Saul, and an evil spirit from the Lord troubled him--His own gloomy reflections, the consciousness that he had not acted up to the character of an Israelitish king, the loss of his throne, and the extinction of his royal house, made him jealous, irritable, vindictive, and subject to fits of morbid melancholy.”

“Departed - God took away that prudence, and courage, and alacrity, and other gifts wherewith be had qualified him for his public employment. From the Lord - That is, by God's permission, who delivered him up to be buffeted of Satan. Troubled - Stirred up in him unruly and tormenting passions; as envy, rage, fear, or despair. He grew fretful, and peevish, and discontented, timorous and suspicious, frequently starting and trembling. 1 Kings (1 Samuel) 16:16”

“16:14–31:13 Saul’s kingship continued its downward spiral after God’s Spirit departed from him. His reign ended in shame and defeat (ch 31). 16:14 Spirit . . . left Saul: In contrast with David’s receiving the Spirit (see “The Spirit’s Presence” Theme Note). • The Lord sent a tormenting spirit as a consequence of Saul’s disobedience (see also 18:10; 19:9; cp. Judg 9:23; Rom 1:28-29).”

“the Spirit: Sa1 11:6, Sa1 18:12, Sa1 28:15; Jdg 16:29; Psa 51:11; Hos 9:12 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…”

“David's Introduction to the Court of Saul. - Sa1 16:14. With the rejection of Saul on the part of God, the Spirit of Jehovah had departed from him, and an evil spirit from Jehovah had come upon him, who filled him with fear and anguish. The "evil spirit from Jehovah" which came into Saul in the place of the Spirit of Jehovah, was not merely an inward feeling of depression at the rejection announced to him, which grew into melancholy, and occasionally broke out in passing fits of insanity, but a higher evil power, which took possession of him, and not only deprived him of his peace of mind, but stirred up the feelings, ideas, imagination, and thoughts of his soul to such an extent that at…”
