Something Old in the New Testament

What could be 'old' in the New Testament?

This

Romans 9:4 -

the people of Israel. Theirs is the adoption to sonship; theirs the divine glory, the covenants, the receiving of the law, the temple worship and the promises.

Or in the King James Version:

Who are Israelites; to whom pertaineth the adoption, and the glory, and the covenants, and the giving of the law, and the service of God, and the promises;

One of those "promises" surely includes the one, repeated often to Abraham, Yitzhak, Yaakov, Moshe and all of the congregation of Israel, that the Land of Israel, which is known as Judea and Samaria (Acts 8:1), is the Jewish national home.
