Fisherman:
Was 70 CE not year 70 either?
Red herring. “70 CE” isn’t mentioned in the Bible, and wasn’t called that at the time. The fact that the year Jerusalem was destroyed by the Romans later came to be called 70 is a coincidence.
How many years exactly did the land not keep Sabbath is not known but the sentence imposed was 70 years of desolation so the land could rest.
Your interpretation of the verse regarding how paying sabbaths relates to exile is entirely wrong as explained here.
537BCE+70=607BCE,
Jeremiah explicitly identifies the 70 years as a period of nations serving Babylon, not a period of exile. He also says exile was a punishment for refusing to serve Babylon rather than what ‘serving Babylon’ means. And he also says attention would be given to the Jews’ return only after the 70 years had already ended. And 2 Chronicles says servitude to Babylon ended when Persia began to reign. But you don’t actually care what the Bible says.
assuming 537 marks the end of the desolationThe Jews returned in 538, not 537. The fact that you need to ‘assume’ otherwise is very telling. 😂
