I will study this a little later. Hebrew yanuka just means a 'child rabbi' although it implies a child prodigy.
As to being a 'false prophet' - and stars & stripes can correct me on this if need be - I don't think Biblical prophecy calls on 'THE' False Prophet to perform miracles; that would indicate the office of Messiah - or false messiah. Of course 'miracles' need to be verified, such as the Catholic Church has pursued over the centuries.
More later. 😇
Matthew 24:23-35
“Then if anyone says to you, ‘Look! Here is the Messiah!’ or ‘There he is!’—do not believe it. For false messiahs and false prophets will appear and produce great signs and omens, to lead astray, if possible, even the elect. Take note, I have told you beforehand. So, if they say to you, ‘Look! He is in the wilderness,’ do not go out. If they say, ‘Look! He is in the inner rooms,’ do not believe it. For as the lightning comes from the east and flashes as far as the west, so will be the coming of the Son of Man. Wherever the corpse is, there the vultures (Eagles) will gather.
“Immediately after the suffering of those days
the sun will be darkened,
and the moon will not give its light;
the stars will fall from heaven,
and the powers of heaven will be shaken."Â
Then the sign of the Son of Man will appear in heaven, and then all the tribes of the earth will mourn, and they will see ‘the Son of Man coming on the clouds of heaven’ with power and great glory. And he will send out his angels with a loud trumpet call, and they will gather his elect from the four winds, from one end of heaven to the other."
**"Wherever the corpse is, there the vultures (Eagles) will gather" The corpse probably refers to the state of Israel, the Eagles may refer to the eagle on the Roman Standard and the future revolt and Roman conquest in 66AD.
