The “prophet” proclaimed the message given to him, as the “seer” beheld the vision of God. (See Num. 12:6, 8.) Thus a prophet was a spokesman for God; he spake in God’s name and by his authority (Ex. 7:1). He is the mouth by which God speaks to men (Jer. 1:9; Isa. 51:16), and hence what the prophet says is not of man but of God (2 Pet. 1:20, 21; comp. Heb. 3:7; Acts 4:25; 28:25).
