Besides, when I write it out and point to the scripture you say it's obscure and too long winded.

"A mixed multitude went out of Egypt."
Israel was formed at the covenant at Sinai. Many people became Israel who were not sons of Jacob / Israel.

St Paul and other NY authors distinguish between Judaeans and Israel.

St Paul and St Peter both refer to gentiles as Israel. St. Paul tells gentiles "our fathers" followed the cloud. St Peter quotes Deuteronomy - you are a royal priesthood - to non- Judaeans. Romans 11 is about the tribes who were lost to the nations.

"26 So, if a man who is uncircumcised keeps the precepts of the law, will not his uncircumcision be regarded as circumcision?"
