Relegating Israel to the dustbin of history, by either hoping or believing that God has rejected or else replaced her, is not something that only began with Gentile Christian history. God’s dealings with His people have perplexed other people for millennia up until these end times of the last days. Hear what the LORD let Jeremiah know about 700 years before the destruction of the Temple in Jerusalem by the Romans in 70 AD:
Jer 33:23-26 Moreover the word of YHVH came to Jeremiah, saying, “Have you not considered what these people have spoken, saying, ‘The two families (i.e., David’s for the kingship, and the Levites for the priesthood) which YHVH has chosen, He has also cast them off!‘? Thus they have despised My people, as if they should no more be a nation before them.
“Thus says YHVH: ‘If My covenant is not with day and night, and if I have not appointed the ordinances of heaven and Earth, then I will cast away the descendants of Jacob and David My servant, so that I will not take any of his descendants to be rulers over the the descendants of Abraham, Issac, and Jacob. For I will cause their captives to return, and will have mercy on them.'”
