I see, so you say this will all happen when the messiah comes.
Your link claims that Leviticus 26:44 proves that God’s covenant with Jews is eternal.
The only problem is it does not say it is an eternal covenant at all:
44 Yet in spite of this, when they are in the land of their enemies, I will not reject them or abhor them so as to destroy them completely, breaking my covenant with them. I am the Lord their God.
He says he will not break the covenant, he does not say it is eternal or will never be replaced.
