'Prophet' in the Bible

and all Israel know, from Dan even unto Beer-Sheba, that Samuel is established for a prophet to Jehovah.

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.'

And Gad the prophet saith unto David, 'Thou dost not abide in a fortress, go, and thou hast entered for thee the land of Judah;' and David goeth and entereth the forest of Hareth.
