In religion, a prophet or prophetess is an individual who is regarded as being in contact with a divine being and is said to speak on behalf of that being, serving as an intermediary with humanity by delivering messages or teachings from the supernatural source to other people. The message that the prophet conveys is called a prophecy.
Claims of prophethood have existed in many cultures and religions throughout history, including Judaism, Christianity, Islam, ancient Greek religion, Zoroastrianism, Manichaeism, Hinduism, and many others.
The English word prophet is the transliteration of a compound Greek word derived from pro (before/toward) and phesein (to tell); thus, a προφήτης (prophḗtēs) is someone who conveys messages from the divine to humans, including occasionally foretelling future events. In a different interpretation, it means advocate or speaker.
In Hebrew, the word נָבִיא (nāvî), "spokesperson", traditionally translates as "prophet". The second subdivision of the Tanakh, (Nevi'im), is devoted to the Hebrew prophets. The meaning of Navi is perhaps described in Deuteronomy 18:18, where God said, "...and I will put My words in his mouth, and he shall speak unto them all that I shall command him." Thus, the Navi was thought to be the "mouth" of God. The root nun-bet-alef ("Navi") is based on the two-letter root nun-bet which denotes hollowness or openness; to receive transcendental wisdom, one must make oneself "open".
Nevi'im and Prophets in Judaism
In addition to writing and speaking messages from God, Israelite or Judean nevi'im ("spokespersons", "prophets") often acted out prophetic parables in their life. For example, in order to contrast the people's disobedience with the obedience of the Rechabites, God has Jeremiah invite the Rechabites to drink wine, in disobedience to their ancestor's command. The Rechabites refuse, for which God commends them. Other prophetic parables acted out by Jeremiah include burying a linen belt so that it gets ruined to illustrate how God intends to ruin Judah's pride.
