The blood covenant of Christ was applied to every. Jew and Gentile.You need to get a proper understanding of the Church. Please read and study Romans 11 and all other Scriptures about the Church.
1. The New Covenant was given to Israel (the kingdoms of Israel and Judah, or the twelve tribes of Israel).
2. The Lord Jesus Christ is the Mediator of the New Covenant, since it was His shed blood which ratified this Covenant.
4. The New Covenant went into effect the day Christ died, and said "It is finished". The tearing of the temple veil in two meant the end of the Old Covenant.
5. Fifty days after the crucifixion, the Holy Spirit was poured out on earth to fulfill the promise of the Spirit under the New Covenant.
6. Three thousand Jews were saved on the day of Pentecost, and this was the beginning of the Church under the New Covenant.
7. Therefore the New Covenant was applied immediately to Israel, but would not be limited to Israel.
8. Peter was sent to the home of the Gentile Cornelius to begin the grafting of Gentiles into the Church. Therefore the Church consists of the root and tree of believing Israel, and Gentiles are called branches grafted from the wild olive tree into the good olive tree.
9. The New Covenant is an everlasting covenant, which means that after the Second Coming of Christ, all unbelieving Jews will be gathered to the land of Israel, and a believing remnant will be placed within greater Israel during the Millennium (and beyond). They will all be regenerated and receive the gift of the Holy Spirit.
10. There is only one New Covenant in the blood of Christ, and that covers both the Church and redeemed and restored Israel.
The new covenant to the houses of Israel and Judah is only applied to those two houses. No Gentiles.
The church is everyone. The body of Christ is church and Israel. Coheirs, not one heir.
The church is the bride of Christ. Israel is the wife of God.
As I said, in the MK the stone Temple returns. Animal sacrifices return.
You have animal sacrifices coexisting with the blood of Christ.
In the OT blood was a future promise. In the church it was immediate via the baptism of the Holy Spirit. In the MK is again future promise, thus the blood sacrifices on the alter.
You are so obsessed with this as you are with the KJV and both spirit and soul alive in heaven for the same person, but in different places.
