'Seer' in the Bible

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

And as they went up the hill to the city, they found young maidens going out to draw water, and said unto them, Is the seer here?

Then Saul drew near to Samuel in the gate, and said, Tell me, I pray thee, where the seer's house is.

And Samuel answered Saul, and said, I am the seer: go up before me unto the high place; for ye shall eat with me to day, and to morrow I will let thee go, and will tell thee all that is in thine heart.
