It speaks of "leaving the land of the Chaldeans." And Stephen is talking about Abraham. What does that have to do with the Chaldean language (Hebraisti) of the Jews in the 1st century AD? Seems like you are drowing and grababing every straw you can find. Pathetic.
LOLOL --
So then the Greek "Chaldaios" means "Chaldean", and you are saying that the Greek "Hebraisti" also means "Chaldean"??? At first you claimed that the Greek "Hebraisti" meant "Aramaic", and then "Chaldean".
And now we find out that the Greek has two words for "Chaldean", and not one word at all for "Hebrew"????? Does anyone living in the real world outside of the land of Greek mythology believe that???
Perhaps we should heed that ancient advice: Beware of Greeks bearing their own dictionaries.
