David,
Who is the Mateh Moshe?
This seems to be a clear souce for a gimmel degusha, a gimmel with a dagesh.
I found a few sources in the Amidah prayer, the Shmoneh-Esray, where Jews beseech G-d to deliver them from exile, and other places in the Jewish prayerbook.

To which Rebbe are you referring? A rebbe simply means 'my teacher'. Don't you know that? King David even called his enemy "rebbe", just because he taught him something (Avot). The Lubavitcher Rebbe called everyone 'rebbe', except one person. He called him, "hahu eesh", "that guy" to avoid speaking "lashon hora", malicious speech.
Maybe, geulah has a gimmel with a dagesh, maybe not.
John, can you search your data base if the geulah ever appears in the Tanach?
