'Seer' in the Bible

Formerly in Israel, thus said the man in his going to seek God, 'Come and we go unto the seer,' for the 'prophet' of to-day is called formerly 'the seer.'

They are going up in the ascent of the city, and have found young women going out to draw water, and say to them, 'Is the seer in this place?'

And Samuel answereth Saul and saith, 'I am the seer; go up before me into the high place, and ye have eaten with me to-day, and I have sent thee away in the morning, and all that is in thy heart I declare to thee.
