Somewhere toward the end of Rosh HaShanah, when discussing Techias HaMeisim, the Gemara poses a Hava Aminah that only those in Eretz Yisrael would be awakened. The Gemara rejects this, saying that people like Moshe wouldn't have a share in Yimos HaMashiach if that were the case. I believe that, if not the Gemara itself, some Peirush on that Gemara adds that Moshe will once again lead the Dor HaMidbar and this time actually make it to Eretz Yisrael. I apologize for not being more specific about the sources; it's been a long time since I've learned Rosh HaShanah; I'll try, bli neder, to update this with sources over the next couple of days.
