Time & again in the OT the restoration of Isarel scattered among the nations is tied to the salvation of the Gentiles. They’re woven together. It is wrong to miss the theme of the restoration of Israel. But it is also wrong to untether it from the salvation of the nations.
Recently saw it in Isaiah 11–12
Note, too how Paul is happy to skip/collapse the middle step of restoration, for example in Romans 9.
