According to the Radak the first posuk:
?????? ???? ???? ????? ?????? ?? ??? ????
is saying that through the yeshua of klal yisroel after milchemes gog umagog, the goyim will also have a yeshua because they will serve Hashem too.
The second pasuk:
????? ???? ?????
the Radak says is also talking about by the geulah. He compares it to Yeshaya 2:3 ‘????? ???? ???? ????? ??? ????? ?? ?? ?. I assume he means that they will follow in our ways come moshiach.
Maybe the mekor for saying that or lagoyim is someting that we are supposed to be now is elsewhere.
