False? I just showed you from the context that it Israel.
3 For I could wish that myself were eaccursed from Christ for my brethren, my kinsmen according to the flesh: 4 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; 5 Whose are the fathers, and of whom as concerning the flesh Christ came, who is over all, God blessed for ever. Amen.

Look at what Paul said. The adoption belongs to Israel. You were saved under the New Covenant, correct? Who was the New Covenant made with? It was made with Israel.
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:
32 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:
33 But this shall be the covenant that I will make with the house of Israel;
After those days, saith the LORD,
fI will put my law in their inward parts,
And write it in their hearts;
And will be their God,
And they shall be my people.
34 And they shall teach no more every man his neighbour, and every man his brother, saying,
Know the LORD:
For they shall all know me,
From the least of them unto the greatest of them, saith the LORD:
For I lwill forgive their iniquity,
And I will remember their sin no more.
