(Formerly in Israel, when a man went to inquire of God, thus he spoke, Come, and let us go to the seer: for he that is now called a Prophet was formerly called a Seer.)

Hippolytus of Rome
AD 235
For with what reason should the prophet be called a prophet, unless he in spirit foresaw the future? For if the prophet spoke of any chance event, he would not be a prophet then in speaking of things which were under the eye of all. But one who sets forth in detail things yet to be, was rightly judged a prophet. Wherefore prophets were with good reason called from the very first “seers.”
