'Seer' in the Bible

(In earlier times in Israel, when a man went to inquire of God, thus he said, "Come, and let us go to the seer;" for he who is now called a prophet was before called a Seer.)

As they went up the ascent to the city, they found young maidens going out to draw water, and said to them, "Is the seer here?"

Samuel answered Saul, and said, "I am the seer. Go up before me to the high place, for you shall eat with me today. In the morning I will let you go, and will tell you all that is in your heart.
