8. Now—Greek, "But"; it is no wonder there should be now such opponents to the truth, for their prototypes existed in ancient times [Alford].
Jannes … Jambres—traditional names of the Egyptian magicians who resisted Moses (Ex 7:11, 22), derived from "the unwritten teaching of the Jews" [Theodoret]. In a point so immaterial as the names, where Scripture had not recorded them, Paul takes the names which general opinion had assigned the magicians. Eusebius [Preparation of the Gospel], quotes from Numenius, "Jannes and Jambres were sacred scribes (a lower order of priests in Egypt) skilled in magic." Hiller interprets "Jannes" from the Abyssinian language a trickster, and "Jambres" a juggler" (Ac 13:8).
