Messiah-In Judaism, the Messiah (מָשִׁיחַ Standard Hebrew Mašíaḥ Arabic: Al-Masiḥ, المسيح), Tiberian Hebrew Māšîªḥ, Aramaic משיחא) initially meant any person who was a prophet of God. In English today, in religious contexts, it is used in two major contexts: the anticipated saviour of the Jews, which has to come in the future to bring ultimate peace on earth; and secondly, the one who is anticipated as, regarded as, or professes to be a saviour or liberator. Jews, however, do not generally use the word "saviour" in reference to the messiah, primarily because of the Christian connotation of the word "saviour," and the sense in which that word is used by Christianity".

Prophet-"In religion, a prophet (or prophetess) is a person who has directly encountered the numinous and serves as an intermediary with man for the divine. Prophets existed in many ancient cultures, including the Sybilline and Delphic Oracles in Ancient Greece, the Völuspá in Old Norse, Zoroaster in Persia, and many others. In Abrahamic religion, a prophet is seen as a person who has encountered, and speaks as a formal representative of, God; they are seen to found a new religion based on their teachings from God."  Source:Wikipedia
