If the New Testament was originally written in Hebrew and Aramaic there would have been no point in those verses you quote, such as
J
ohn 5:2
Now there is in Jerusalem by the sheep
gate a pool, which is called in
Hebrew Bethesda, having five porches.
I have never heard or read that the whole New Testament was originally written in Hebrew/Aramaic. I came across this site:
Was the New Testament Written in Hebrew, Aramaic, or Greek? It includes the following paragraph:
"With the conquest of Alexander the Great in the late fourth century, Greek gained prominence as the common language of government, trade, and elite culture throughout the Eastern Mediterranean, including Judea and Galilee. By the third century BC at the latest, the Jewish expatriate community in Egypt had largely lost the ability to speak Hebrew and/or Aramaic, and so they translated the books of the Hebrew Bible into their then-native Greek. These translations—collectively called the “Septuagint”—became the main Scriptures used in the Jewish diaspora, the Jewish people living outside of the land of Israel. Many Jewish works from the diaspora, as well as some from Judea, were also written in Greek in this period."
New Testament in Hebrew
Yahshua understood Hebrew, although in his everyday life may have been conducted in Aramaic. The first four books of the New Testament, the Gospels of Matthew and Mark records Yahshua using Aramaic terms and phrases. In Luke 4:16, he was shown reading Hebrew from the Bible at a synagogue.
Luke 23:38. KJ21
And a superscription also was written over Him in letters of Greek and Latin and Hebrew: This Is The King Of The Jews.
The Jews in Jerusalem and Judaea in the period from 400 BCE to 150 CE spoke Mishnaic Hebrew.
“Matthew put down the words of the Lord in the Hebrew language, and others have translated them, each as best he could.”-Papias, bishop of Hierapolis, c. 150 A.D.
"Matthew, indeed, produced his Gospel written among the Hebrews in their own dialect.”– Irenaeus (120-202 A.D.)
Bishop of Lions, France.
“The first Gospel composed in the Hebrew language, was written by Matthew…for those who came to faith from Judaism.”
Origen (225 A.D.)
“Matthew had first preached to the Hebrews, and when he was about to go to others also, he transmitted his Gospel in writing in his
native language”
(Ecclesiastical History III 24, 6)
“Matthew collected and wrote the oracles in the Hebrew language”
(Ecclesiastical History, III, 39, 16.)
“both the Church Fathers as well as the recently
discovered Dead Sea Scrolls state quite clearly
and without any equivocation that Hebrew WAS the
language spoken and written at the time of the
Messiah and his Disciples.”

“the issue of the New Testament being written
in Greek or Aramaic was non-existent prior to
the Fourth or Fifth Century A.D. It has been
a rather modern theory based upon anti-semitism
which is a hatred of anything Jewish.”

“There were debates concerning the destruction of the New Testament scrolls, because they contained the divine Name of God in
Hebrew (Yahwah).” The debate clearly documents that the gospels were written in Hebrew.
The Babylonian Talmud (Shabbat 116a),The Jerusalem Talmud (Shabbat 15c),
And the Tosefta (Shabbat 13:5).
Yahwah's name was in the original New Testament scriptures
After killing Hebrew Christians, the Jews would take the New Testament scripture written in Hebrew, and carefully cut the name of God out. Then they would place the divine name in a safe place to keep. Following that, they then would burn the remainder of the scrolls in a fire.
Rabbi Yose who lived during the second century AD states that,
"One cuts out the reference to the Divine Name which are in them [the New Testament writings] and stores them away, and the rest burns." One of his characteristic sayings is,
"He who proclaimed the coming of the Messiah,[John] and he who hated scholars [Yahshua] and his disciples; and that false prophet and those slanderers, will have no part in the future world." According to
Wilhelm Bacher this was directed against the Hebrew Christians. And so it is an established fact then, that the Disciples of Christ did in fact write the Holy Name of God into the original New Testament.
