TSK · Exodus 8:7

The magicians of Egypt did the same thing with their enchantments; and Pharaoh's heart was hardened, and he didn't listen to them; as Yahweh had spoken.

For there will arise false christs, and false prophets, and they will show great signs and wonders, so as to lead astray, if possible, even the chosen ones.

Even as Jannes and Jambres opposed Moses, so do these also oppose the truth; men corrupted in mind, who concerning the faith, are rejected.
