John Trapp on Isaiah 45:7

Ver. 7. I form the light and create darkneſſe] ſc. By withdrawing the light, whence darkneſs ſucceedeth; ſo doth miſery when God withholdeth mercy. But what an odd or rather mad conceit was that of the Manichees, that there were two beginnings of things, a good one, and an evil! that the latter was the God of the Old Teſtament, and the former of the New! that the God of the Old Teſtament did good by accident and occaſionally, but created evil of himſelf, even evil of ſin! for ſo they miſtook this text, which is to be underſtood of evil of puniſhment only, (ſee Am. 3.6. Lam. 3.38) which he inflicteth on evil-doers for the manifeſtation of his juſtice and power, ac propterea recte, Vide Aug. contra Julian. l. 3. c. 8. & non male eo pacto quo per nos mala male fiunt.

I make peace and create evil] Evil, that is, war, by a ſpecialty, and [non-Latin text not transcribed]. O mega noſtrorum Mors eſt, Mars Alpha malorum. Sin, Satan and War have all one name: evil is the beſt of them. The beſt of ſin is deformity, of Satan enmity, of War miſery.
