What is a Prophet?
Many people today think of a prophet as any person who sees the future. While the gift of prophecy certainly includes the ability to see the future, a prophet is far more than just a person with that ability.
A prophet is basically a spokesman for G-d, a person chosen by G-d to speak to people on G-d's behalf and convey a message or teaching. Prophets were role models of holiness, scholarship and closeness to G-d. They set the standards for the entire community.
The Hebrew word for a prophet, navi (Nun-Beit-Yod-Alef) comes from the term niv sefatayim meaning "fruit of the lips," which emphasizes the prophet's role as a speaker.
The Talmud teaches that there were hundreds of thousands of prophets: twice as many as the number of people who left Egypt, which was 600,000. But most of the prophets conveyed messages that were intended solely for their own generation and were not reported in scripture. Scripture identifies only 55 prophets of Israel.
A prophet is not necessarily a man. Scripture records the stories of seven female prophets, listed below, and the Talmud reports that Sarah's prophetic ability was superior to Abraham's.
A prophet is not necessarily a Jew. The Talmud reports that there were prophets among the gentiles (most notably Balaam, whose story is told in Numbers 22), although they were not as elevated as the prophets of Israel (as the story of Balaam demonstrateshttp://www.jewfaq.org/prophet.htm
