The role of a prophet in the biblical context is to serve as a spokesperson for God, delivering His messages to the people. The Old Testament contains numerous prophecies that foretell the coming of the Messiah, who would fulfill the office of a prophet. These prophecies are seen as being fulfilled in Jesus Christ, who is recognized in the New Testament as the ultimate prophet, priest, and king.

Deuteronomy 18:15-19
One of the clearest predictions of Christ exercising the office of a prophet is found in Deuteronomy 18:15-19. Moses speaks to the Israelites, saying, "The LORD your God will raise up for you a prophet like me from among your brothers. You must listen to him" (Deuteronomy 18:15). This passage is understood to refer to Jesus, who, like Moses, would be a mediator between God and His people. The New Testament confirms this interpretation in Acts 3:22-23, where Peter cites this prophecy in reference to Jesus.

Isaiah 61:1-2
The book of Isaiah also contains prophecies that are seen as predicting Christ's prophetic ministry. Isaiah 61:1-2 states, "The Spirit of the Lord GOD is upon me, because the LORD has anointed me to bring good news to the poor. He has sent me to bind up the brokenhearted, to proclaim liberty to the captives and recovery of sight to the blind, to set free those who are oppressed, to proclaim the year of the LORD’s favor" . Jesus directly applies this prophecy to Himself in Luke 4:18-21, when He reads from the scroll of Isaiah in the synagogue and declares, "Today this Scripture is fulfilled in your hearing."

Psalm 110:4
While primarily a messianic psalm that emphasizes the priestly and kingly roles of the Messiah, Psalm 110:4 also implies a prophetic function. "The LORD has sworn and will not change His mind: 'You are a priest forever in the order of Melchizedek'" . The New Testament book of Hebrews elaborates on this, presenting Jesus as the ultimate fulfillment of this prophecy, who not only serves as a priest but also speaks God's word as a prophet.

Zechariah 9:9
Zechariah 9:9 is another prophetic passage that is often associated with Christ's role as a prophet. "Rejoice greatly, O daughter of Zion! Shout in triumph, O daughter of Jerusalem! See, your king comes to you, righteous and victorious, humble and riding on a donkey, on a colt, the foal of a donkey" . This prophecy is fulfilled in the New Testament during the Triumphal Entry, as recorded in Matthew 21:4-5, where Jesus enters Jerusalem, symbolically enacting His role as the prophesied king and prophet.

Conclusion
The Old Testament prophecies concerning the coming Messiah consistently point to a figure who would embody the roles of prophet, priest, and king. Jesus Christ is recognized in the New Testament as the fulfillment of these prophecies, exercising the office of a prophet by proclaiming God's word, revealing divine truth, and calling people to repentance and faith.Deuteronomy 18:15
