“False Messiah Christs
Will appear!
False prophets
Will appear!
They will produce
Signs!
They will produce
Omens
To lead astray,
If possible,
The elect.”
ἐγερθήσονται δὲ ψευδόχριστοι καὶ ψευδοπροφῆται καὶ ποιήσουσιν σημεῖα καὶ τέρατα πρὸς τὸ ἀποπλανᾶν εἰ δυνατὸν τοὺς ἐκλεκτούς·
This is almost word for word, in Matthew, chapter 24:24. Mark said that both false or pseudo-Christs and false and pseudo-prophets would appear (ἐγερθήσονται δὲ ψευδόχριστοι καὶ ψευδοπροφῆται). They would give signs and wonders (καὶ ποιήσουσιν σημεῖα καὶ τέρατα), in order to deceive, if possible, even the elect or the chosen ones (πρὸς τὸ ἀποπλανᾶν εἰ δυνατὸν τοὺς ἐκλεκτούς). The 3 synoptic gospels often warned against people who might lead them astray. Some people would come saying that they were the Messiah Christ in order to deceive them. Apparently, there were quite a few deceptive Jewish messianic leaders who were saying that they were the Christ Messiah. John the Baptist was an example of a messianic leader in the 1st century CE. Other political Jewish leaders had messianic ambitions also, especially those who led the revolt against the Romans in the 2nd half of the 1st century. Jesus was warning against all of them.
