They called Chaldee Hebraisti (Hebrew tongue). Now, even a first a grade biblical scholar knows that Chaldee was Aramaic. It is referenced four times in the Gospel of John as such, inlcuidng the inscription on the Cross, which was not in (Biblical) hebrew, but in Chaldee (Aramaic).
Western Aramaic was also called "Syriac" or the Syrian tongue and Eastern Aramaic was Chaldean
Chaldee was the language spoken by the Jews, which the Aramaic, not Biblical Hebrew.
Should we change the title of the Book of Hebrews to the Book of the Chaldeans or the Book of the Syrians or the Book of the Arameans???? Why is it so hard to call the language of the Jews what it is and was: HEBREW.
"And Pilate wrote a title, and put it on the cross. And the writing was JESUS OF NAZARETH THE KING OF THE JEWS. This title then read many of the Jews: for the place where Jesus was crucified was nigh to the city: and it was written in Hebrew ["Hebraisti"] , and Greek, and Latin." [[John 19:19-20]
If the author John meant "Chaldee" he would have written "Chaldee", and if he meant "Aramaic", he would have written "Aramaic", but he didn't because it wasn't. It was called HEBREW -- and you cannot erase it from either history or the Greek scriptures.
