Then you should be able to provide a verse where it says that it was promised to anyone other than the house of Israel.

All of those of the houses of Judah and srael will know the Lord and all of them will receive the forgiveness of their sins. We can also know that the promise is made to Israel after the flesh because it was that entity who broke the covenant which God made with their fathers:
"Behold, the days come, saith the LORD, that I will make a new covenant with the house of Israel, and with the house of Judah: Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the LORD" (Jer.31:31-32).
The New Covenant will be made with those who broke the Covenant which God made with "their fathers." So that can only be referring to Israel "after the flesh." It was Israel "after the flesh" who broke the Covenant which God made with "their fathers." Also, it was Israel "according to the flesh" who was brought out of the land of Egypt.
Common sense dictates that the New Covenant promised to the house of Israel has not yet been fulfilled because not all of the sins of Israel "after the flesh" have been forgiven.
