The question is irrelevant. You are trying to displace the true meaning of the "new" covenant, to keep 2P2P alive.
The problem with 2P2P is that there is no need for a 2nd program anymore. There is no need, because it was the child-trainer/governess stage of spiritual life for believers. There is no need because God always was going to make Christ a priest/mediator in the 'order' of THE LORD/KING OUR RIGHTEOUSNESS. There is no need because Christ was the other party of the covenant, and acted as a representative for us, as Adam did negatively, Rom 5B. There is no need because there are no NT 'end of time' passages that hinge on events in Israel.
2P2P has no roots, no place, any more.
Some people think it is needed to 'prove' God. Yet it still does not come down to the land promise. God is proved by a number of things. This week I heard excellent geologic proof for Noah's global deluge and this exists to this day; there is no theological confusion to sort through to access it. God is not a liar because of a change of covenant, or priesthood or 'land promise.' And the NT corrects the land promise to how it would be true in Christ anyway; he is the Sabbath-rest of which the arrival in Canaan was a shadow and picture.
