The major prophets of the Hebrew Bible are Abraham, Isaac, Jacob, Moses and Aaron. Of these, Judaism considers Moses the greatest. In Christianity, Isaiah, Jeremiah, Daniel and Ezekial are also considered major prophets.
There are also many minor prophets, some of whom straddle the Jewish and Christian faiths and some who are exclusive to each. In both Judaism and Christianity, those considered prophets are considered to have an almost mystical understanding of God's writings as well as his spiritual plan for mankind. They are key figures in the development of the Old Testament storyline of the impending arrival of a Messiah who will save all of mankind. In Judaism, this individual has yet to come. In Christianity, the Messiah is the New Testament figure Jesus Christ.
The prophets take up leadership roles within their faiths as preachers, teachers, rabbis and those who oversee the development of tenets. Biblical prophets are also not exclusively male. Several female prophets are recognized in the Hebrew Bible. Many of the books of both the Hebrew and Christian Bibles are named for the prophets whose stories they tell. The exceptions, however, are the major prophets of the Hebrew Bible, whose stories are told within the first two books of Genesis and Exodus.
