Isaiah 19:14

“The Lord hath mingled a perverse spirit in the midst thereof, &c.] A spirit of error, as the Targum, Septuagint, and Arabic versions; or of giddiness, as the Vulgate Latin: this he mingled in a cup for them, and poured it out, and gave them it to drink; and an intoxicating cup it was, such as men are made drunk with; to which the allusion is, as the last clause of the verse shows; so that the infatuation and want of wisdom in their counsels were from the Lord; who, because of the vain boasts of their wisdom in righteous judgment, gave them up to judicial blindness, stupidity, and folly: and they have caused Egypt to err in every work thereof; both in religious and civil affairs, leading them…”

“err in every work thereof--referring to the anarchy arising from their internal feuds. HORSLEY translates, "with respect to all His (God's) work"; they misinterpreted God's dealings at every step. "Mingled" contains the same image as "drunken"; as one mixes spices with wine to make it intoxicating (Isa 5:22; Pro 9:2, Pro 9:5), so Jehovah has poured among them a spirit of giddiness, so that they are as helpless as a "drunken man."”

“The Lord hath mingled - The word מסך mâsak, “to mingle,” is used commonly to denote the act of mixing spices with wine to make it more intoxicating Proverbs 9:2, Proverbs 9:5; Isaiah 5:22. Here it means that Yahweh has poured out into the midst of them a spirit of giddiness; that is, has produced consternation among them. National commotions and calamities are often thus traced to the overruling providence of God (see the note at Isaiah 19:2; compare Isaiah 10:5-6). A perverse spirit - Hebrew, ‘A spirit of perverseness.’ The word rendered ‘perverse’ is derived from עוה ‛âvâh, “to be crooked or perverted.” Here it means, that their counsels were unwise, land such as tended to error and…”

“Mingled - Or, hath poured out or given them to drink. To err - In all their designs and undertakings. Staggereth - When he is so drunk, that he reels to and fro, and vomits up his drink. Isaiah 19:15”

“hath mingled: Isa 19:2, Isa 29:10, Isa 29:14, Isa 47:10, Isa 47:11; Kg1 22:20-23; Job 12:16; Eze 14:7-9; Th2 2:11 perverse spirit: Heb. spirit of perverseness as a: Isa 28:7, Isa 28:8, Isa 29:9; Job 12:25; Jer 25:15, Jer 25:16, Jer 25:27, Jer 48:26 Isaiah 19:15”

“In Isa 19:14 and Isa 19:15 this state of confusion is more minutely described: "Jehovah hath poured a spirit of giddiness into the heart of Egypt, so that they have led Egypt astray in all its doing, as a drunken man wandereth about in his vomit. And there does not occur of Egypt any work, which worked, of head and tail, palm-branch and rush." The spirit which God pours out (as it also said elsewhere) is not only a spirit of salvation, but also a spirit of judgment. The judicial, penal result which He produces is here called עועים, which is formed from עועו (root עו, to curve), and is either contracted from עועוים, or points back to a supposed singular עועה (vid., Ewald, 158, b).
