I don't know but if you go off of the witness of the gospels there was a jewish crowd there and they are the ones that Matthew referred to
If you take Matthew's Greek for how it's represented the Triumphal entry, you could readily point to the section you refer to as being that those who were present at Jesus' Crucifixion hurled insults at Him in the same way as the chief priests and teachers of the Law and elders had -- at the time of the writing. In other words, "Expect this same argument from the elders, teachers, even the chief priests. It was adopted from the insults Jesus heard from passersby at His crucifixion -- three days before He was resurrected."
Note the plural: yet there was only one chief priest at the time of the Crucifixion. The only way Matthew could mean this in the plural would be across a period of years -- and Jesus only had a time of hours left before His death.
(NIV)
Matt 27:39 Those who passed by hurled insults at him, shaking their heads 40 and saying, You who are going to destroy the temple and build it in three days, save yourself! Come down from the cross, if you are the Son of God! 41 In the same way the chief priests, the teachers of the law and the elders mocked him. 42 He saved others, they said, but he cant save himself! Hes the king of Israel! Let him come down now from the cross, and we will believe in him. 43 He trusts in God. Let God rescue him now if he wants him, for he said, I am the Son of God. 44 In the same way the rebels who were crucified with him also heaped insults on him. 45 From noon until three in the afternoon darkness came over all the land. 46 About three in the afternoon Jesus cried out in a loud voice, Eli, Eli,[c] lema sabachthani? (which means My God, my God, why have you forsaken me?).[d] 47 When some of those standing there heard this, they said, Hes calling Elijah.
Again, a closer look: it's passersby that hurl the insults. They are definitely not stopping, not an audience. They're not taking it all in. They look up, see the insult at the top of the Cross, and they respond with insults. Cf. John 19:19-20.
Those standing there at the Cross would be a different group than those passing by.
Matthew says that the chief priests, teachers and the elders where also there mocking Jesus so it would be easy to conclude that these leaders would like to have as many witnesses as possible to see Jesus die. The in vers 46 Jesus crys our in Aramaic which those around him thought He was calling out to Elijah. Now it should also be easy to conclude that only those who have heard the law and the prophets would know Elijah don't you think? Do you think that the gentile crowds if there was any there would have known who Elijah was?
It is far more readily concluded that because Jesus had been nailed on a Cross for three hours, losing blood, His speaking was slurred. Only the closest people could hear much of anything.
They were Roman guards, and a tiny group of Jesus' followers. "The 12 disciples" had largely scattered, with limited exceptions.
It is generally accepted that the Gospel of Matthew was originally written in Aramaic and not Greek and was latter translated into Greek.
Why would it be written in Aramaic if no one's speaking Aramaic?
This may be the case but since the Essenes where exterminated in the 1st century one can easily conclude that they did not have a voice in the latter organization of the Hebrew canon.
And yet they had Hebrew Scriptures. During Jesus' time. And were virulently anti-Pharisee, anti-Temple-leadership. They form the foil against the idea that this is just Pharisees or scribes pushing Hebrew language. No, it's not. It's Jesus' contemporaries.
I would not necessarily say that this is the case unless the Jews that showed up at Jesus' cruxifiction, which include's the priests and scribes were not local Jews. I am sure that some there where foreign Jews and I would have to conclude that not all of them were foreign Jews.
That's a possibility. Hellenistic Jewish people were known to make pilgrimages to Jerusalem during Passover.
Untenable? It is a historical fact that the Rabbinic form of Judaism has its roots in the Pharisees. And again from historical record the Essenes had absolutely no imput in the Hebrew canon due to their extermination by the Romans.
So what? Their actions at the time contradicts the idea that Hebrew was not valued outside Pharisaical Judaism. It actually was valued by Palestinian Judaism.
What kind of Jew was Jesus?
