'Seer' in the Bible

(Now it used to be in Israel that whenever someone went to inquire of God he would say, "Come on, let's go to the seer." For today's prophet used to be called a seer.)

As they were going up the ascent to the town, they met some girls coming out to draw water. They said to them, "Is this where the seer is?"

Samuel replied to Saul, "I am the seer! Go up in front of me to the high place! Today you will eat with me and in the morning I will send you away. I will tell you everything that you are thinking.
