Does Judaism believe that Moshe (Moses) is the last Prophet? Is this suggested in the Torah? If he was not the last prophet, but the Torah seems to suggest it, what does that mean?
Maybe you are thinking of Deuteronomy 34:10: "And there hath not arisen a prophet since in Israel like unto Moses" (OJPS). However, he was certainly not the last prophet; in fact the previous verse refers to Joshua being a prophet. Similarly, there are tons of prophets after Moses later in the Tanach. The verse in Deuteronomy simply means that Moshe was the greatest of all the prophets.
