1 Samuel 16:13-15
13. Then Samuel took the horn of oil, and anointed him—This transaction must have been strictly private.
14-18. 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.
1 Kings 22:22
18-23. Did I not tell thee that he would prophesy no good concerning me, but evil?—Since Ahab was disposed to trace this unwelcome truth to personal enmity, Micaiah proceeded fearlessly to tell the incensed monarch in full detail what had been revealed to him. The Hebrew prophets, borrowing their symbolic pictures from earthly scenes, described God in heaven as a king in His kingdom. And as earthly princes do nothing of importance without asking the advice of their counsellors, God is represented as consulting about the fate of Ahab. This prophetic language must not be interpreted literally, and the command must be viewed as only a permission to the lying spirit (Ro 11:34) [CALMET].
Ephesians 6:12
12. Greek, "For our wrestling ('the wrestling' in which we are engaged) is not against flesh," &c. Flesh and blood foes are Satan's mere tools, the real foe lurking behind them is Satan himself, with whom our conflict is. "Wrestling" implies that it is a hand-to-hand and foot-to-foot struggle for the mastery: to wrestle successfully with Satan, we must wrestle with GOD in irresistible prayer like Jacob (Ge 32:24-29; Ho 12:4). Translate, "The principalities . . . the powers" (Eph 1:21; Col 1:16; see on Eph 3:10). The same grades of powers are specified in the case of the demons here, as in that of angels there (compare Ro 8:38; 1Co 15:24; Col 2:15). The Ephesians had practiced sorcery (Ac 19:19), so that he appropriately treats of evil spirits in addressing them. The more clearly any book of Scripture, as this, treats of the economy of the kingdom of light, the more clearly does it set forth the kingdom of darkness. Hence, nowhere does the satanic kingdom come more clearly into view than in the Gospels which treat of Christ, the true Light.
rulers of the darkness of this world—Greek, "age" or "course of the world." But the oldest manuscripts omit "of world." Translate, "Against the world rulers of this (present) darkness" (Eph 2:2; 5:8; Lu 22:53; Col 1:13). On Satan and his demons being "world rulers," compare Joh 12:31; 14:30; 16:11; Lu 4:6; 2Co 4:4; 1Jo 5:19, Greek, "lieth in the wicked one." Though they be "world rulers," they are not the ruler of the universe; and their usurped rule of the world is soon to cease, when He shall "come whose right it is" (Eze 21:27). Two cases prove Satan not to be a mere subjective fancy: (1) Christ's temptation; (2) the entrance of demons into the swine (for these are incapable of such fancies). Satan tries to parody, or imitate in a perverted way, God's working (2Co 11:13, 14). So when God became incarnate, Satan, by his demons, took forcible possession of human bodies. Thus the demoniacally possessed were not peculiarly wicked, but miserable, and so fit subjects for Jesus' pity. Paul makes no mention of demoniacal possession, so that in the time he wrote, it seems to have ceased; it probably was restricted to the period of the Lord's incarnation, and of the foundation of His Church. spiritual wickedness—rather as Greek, "The spiritual hosts of wickedness." As three of the clauses describe the power, so this fourth, the wickedness of our spiritual foes (Mt 12:45). in high places—Greek, "heavenly places": in Eph 2:2, "the air," see on Eph 2:2. The alteration of expression to "in heavenly places," is in order to mark the higher range of their powers than ours, they having been, up to the ascension (Re 12:5, 9, 10), dwellers "in the heavenly places" (Job 1:7), and being now in the regions of the air which are called the heavens. Moreover, pride and presumption are the sins in heavenly places to which they tempt especially, being those by which they themselves fell from heavenly places (Isa 14:12-15). But believers have naught to fear, being "blessed with all spiritual blessings in the heavenly places" (Eph 1:3).
