The Hebrew New Covenant is richer than the Greek, ergo the Hebrew was dumbed-down into Greek and further dumbed-down into English

Matthew 15:24 But He answered and said, “I was not sent except to the lost sheep of the house of Israel.”
Jeremiah 16:19 O Lord, my strength and my fortress, My refuge in the day of affliction,
The Gentiles shall come to You From the ends of the earth and say,
“Surely our fathers have inherited lies, Worthlessness and unprofitable things.”
A 'Greek' New Covenant is just one of many lies...
While it is plausible that the Gospel of Mathew may have originally been in Hebrew, its insane to think the entire New Testament was. I am afraid you have been taken in by some quackery. For example:
No doubt Alexander (the great) instituted Greek as the official language of government in the lands he conquered and Latin was the language of the Roman courts and military but the language spoken by Jewish fishermen was Hebrew, hence the sign written in Hebrew, Greek and Latin.
No, the Jewish fisherman in Rome and Jesus would be speaking a variation of Aramaic. Yes Hebrew was not a dead language, but it was a scholarly language among the Jews who in that time and place spoke Aramaic in their day to day lives. Just as Jews today in America pretty much all speak English but those who are scholarly about Judaism know Hebrew. Even the Book of Daniel is written partly in Hebrew and partly in Aramaic. And Saint Paul as a Roman citizen, Pharisee, and well educated scholar certainly knew Hebrew, Aramaic, and Greek. And as he was primarily spreading the Gospel of Christ to Gentiles, obviously he was not going to do it in Hebrew.
Think for a minute...do you honestly think that Saint Paul was going to write in Hebrew to say the Church in Corinth? That is insane!
In particular the Book of the Revelation of Jesus to Saint John was addressed to the seven churches with lots of Gentiles who likely did not know Hebrew. The obvious language for the time would be Greek, which matches all the evidence from textual criticism of transcripts.
