2 Timothy 3:8

“Now as Jannes and Jambres withstood Moses, etc.] These were not Jews, who rose up and opposed Moses, as Dathan and Abiram did, as some have thought; but Egyptian magicians, the chief of those that Pharaoh sent for, when Moses and Aaron came before him, and wrought miracles; and who did in like manner by their enchantments, (<020711>Exodus 7:11) upon which place the Targum of Jonathan has these words: “and Pharaoh called the wise men and the magicians; and Janis and Jambres, the magicians of the Egyptians, did so by the enchantments of their divinations.” And the same paraphrase on (<020115>Exodus 1:15) calls them by the same names; and this shows from whence the apostle had these names,…”

“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 (Exo 7:11, Exo 7:22), 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…”

“Now as Jannes and Jambres withstood Moses - The names of these two men are not elsewhere mentioned in the Bible. They are supposed to have been two of the magicians who resisted Moses (Exodus 7:11, et al.), and who opposed their miracles to those of Moses and Aaron. It is not certain where the apostle obtained their names; but they are frequently mentioned by the Hebrew writers, and also by other writers; so that there can be no reasonable doubt that their names were correctly handed down by tradition. Nothing is more probable than that the names of the more distinguished magicians who attempted to imitate the miracles of Moses, would be preserved by tradition; and though they are not…”

“Several ancient writers speak of Jannes and Jambres, as the chief of the Egyptian magicians. Men of corrupt minds - Impure notions and wicked inclinations. Void of judgment - Quite ignorant, as well as careless, of true, spiritual religion. 2 Timothy 3:9”

“3:8 Jannes and Jambres are, according to tradition, the names of the Egyptian sorcerers who opposed Moses (see Exod 7:8-13; 8:18; 9:11).”
