get serious...where would the average person at that time learn to read and from whom and with what. I said in an earlier post that people in the government and higher ups in the Jewish religion could read. When you went to a synagogue you listened to a reader...
in public lives there were scribes who, indeed, could read and write, and if you needed their services, you paid for them.
You do not understand the job of the scribe.
The scribes occupied the temple mount daily, listening and writing the words of those claiming to be prophets of Yehova, to be preserved into the future so that should they prove to have been correct their words are included among the prophets.
