Keep in mind what Romans 9:26 says regarding them...
"and, "It will happen that in the place where it was said to them, 'You are not My people,' there they will be called 'sons of the living God.'"
Parallel Hosea 1:10-11- [not to mention in 2:23a (whereas 23b is about "the Gentiles" / Rom9:25)]
10 Yet the number of the Israelites will be like the sand of the sea, which cannot be measured or counted. And it will happen that in the very place where it was said to them, ‘You are not My people,’ they will be called ‘sons of the living God.’
11 Then shall the children of Judah and the children of Israel be gathered together, and appoint themselves one head, and they shall come up [/ascend] out of the land: for great shall be the day of Jezreel.
