While I am one who believes that Jews primarily spoke Hebrew in the first century (and have argued it endlessly hereon), it is simply specious to suggest that Aramaic was not also known and understood. The two are sister languages, readily interchangeable. It would seem more probable that your average Jew couldn't understand/speak Greek rather than Aramaic. And borrowed words (back and forth) then and today, prove it out. Both were living languages, side by side, in close proximity.
In the Hebrew language this god has only be known as Yeshu, which is a foreign name, transliterated. It has no connection to any Hebrew name. The god has never been called anything but Yeshu. The same is probably true in India.
That you will have to source, as every Jew I know, Messianic or not, knows him as Yeshua. Every early text I know of calls him either Yeshua or Jesus.
Aramaic? They spoke that in Syria to the north.
And Arabia to the west, and Egypt to the south. To suggest that Aramaic was afar off is ludicrous.
All the Jews were bilingual then because commerce and government went down in Greek. They needed Aramaic because that was the language of the Jews living in Mesopotamia and there was a lot of interchange. But most people didn’t know it.
Yeshu is a three-letter word just like cat. Yod, shin, vav. Once anyone learns a three-letter word, they never screw it up. That’s the only name the god in the new Greek myth was known by throughout Jewish history.
