TSK · Exodus 8:7

And the magicians of Egypt did in like manner with their enchantments: and Pharaoh's heart was hardened, and he hearkened not unto them; as Jehovah had spoken.

For there shall arise false Christs, and false prophets, and shall show great signs and wonders; so as to lead astray, if possible, even the elect.

And even as Jannes and Jambres withstood Moses, so do these also withstand the truth. Men corrupted in mind, reprobate concerning the faith.
