'Prophet' in the Bible

All Israel from Dan even to Beersheba knew that Samuel was established to be a prophet of Yahweh.

(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.)

The prophet Gad said to David, "Don't stay in the stronghold. Depart, and go into the land of Judah." Then David departed, and came into the forest of Hereth.
