A prophet is someone who is the mouthpiece of God. He stands between God and man to communicate to man the Word of God. When the prophet spoke as the mouthpiece, he was inspired and without error. The prophet, though, is not a puppet or a mindless repeater of what he hears. Instead, he retains his own will, mind, and thoughts as he speaks for God. God would put His words in their mouths (Deut. 18:18; Jer. 1:9). A prophet was God's servant (Zech. 1:6) and messenger (2 Chron. 36:15). The prophecies fell into three categories: concerning the destiny of Israel, the messianic prophecies, and eschatological prophecies. The term Law and Prophets refers to the writings of the OT divided into two categories. The Law is the Pentateuch or Genesis, Exodus, Leviticus, Numbers, and Deuteronomy. The Prophets are all the rest of the OT books.
