I make peace, and create evil; peace between God and men is made by Christ, who is God over all; spiritual peace of conscience comes from God, through Christ, by the Spirit; eternal glory and happiness is of God, which saints enter into at death; peace among the saints themselves here, and with the men of the world; peace in churches, and in the world, God is the author of, even of all prosperity of every kind, which this word includes: "evil" is also from him; not the evil of sin; this is not to be found among the creatures God made; this is of men, though suffered by the Lord, and overruled by him for good: but the evil of punishment for sin, God's sore judgments, famine, pestilence, evil beasts, and the sword, or war, which latter may more especially be intended, as it is opposed to peace; this usually is the effect of sin; may be sometimes lawfully engaged in; whether on a good or bad foundation is permitted by God; moreover, all afflictions, adversities, and calamities, come under this name, and are of God; see Job 2:10,
I the Lord do all these things; and therefore must be the true God, and the one and only one. Kimchi, from Saadiah Gaon, observes, that this is said against those that assert two gods, the one good, and the other evil; whereas the Lord is the Maker of good and evil, and therefore must be above all; and it is worthy of observation, that the Persian Magi, before ZoroastresF13, held two first causes, the one light, or the good god, the author of all good; and the other darkness, or the evil god, the author of all evil; the one they called Oromazes, the other Arimanius; and, as Dr. PrideauxF14 observes,
"these words are directed to Cyrus king of Persia, and must be understood as spoken in reference to the Persian sect of the Magians; who then held light and darkness, or good and evil, to be the supreme Beings, without acknowledging the great God as superior to both;'
and which these words show; for Zoroastres, who reformed them in this first principle of their religion, was after Isaiah's time.
