'Prophet' in the Bible

{To the chief Musician. A Psalm of David; when Nathan the prophet came to him, after he had gone in to Bath-sheba.} Be gracious unto me, O God, according to thy loving-kindness; according to the abundance of thy tender mercies, blot out my transgressions.

We see not our signs; there is no more any prophet, neither is there among us any that knoweth how long.
