<quoted text>Isaiah 17 is entitled,“A Prophecy Against Damascus,” a chapter that details impending disaster, and, in Jeremiah 49, Damascus’ fate
So 160 years after a prophecy was made and concluded the actual prophecy was going to be extended upon as a different location.
To reinforce your machinations today, it can be repeated when ever.
The Assyria took the North, the Babylonians got them and the rest of Israel , what the Lord said about Nebuchadnezzar was a wind down the people are taken away but will come back to be in place for the coming of Christ.
No further prophecy was made concerning the "fate",- I don't even think you know what "fate" is,- of the return in relation to its ending or another beginning after that ending, by any Prophet that the Jew recognized.
So the Chosen People changed when the Jew didn't recognize Christ.
