Wherefore then were ye not afraid to speak against my servant Moses? Num. 12:8.
There are three manifestations of the gift of prophecy described in Scripture. First is the ability by the Holy Spirit's power to speak for God. Sometimes we confine the gift of prophecy to prediction and fulfillment. But it includes anyone who speaks God's truth for a particular time.
The second manifestation includes actual dreams, visions, and predictions. This is not seen as much today. But there is an even more rare function. This has to do with a special-messenger type of prophetic assignment that includes more than prophecy. There have been only three people in the history of God's people who have been known as more than prophets.
Numbers 12:6-8 tells of the first one. The Lord had come down in the cloud and spoken to the people, "Hear now my words: if there be a prophet among you, I the Lord will make myself known unto him in a vision, and will speak unto him in a dream. My servant Moses is not so....With him will I speak mouth to mouth, even apparently, and not in dark speeches; and the similitude of the Lord shall he behold: wherefore then were ye not afraid to speak against my servant Moses?" Here God is indicating to Aaron and Miriam that Moses was not only a prophet but he was more than a prophet. God had a relationship with him and a function for him that included more than the term prophet signified.
The second instance is found in Luke 7:26-28. Jesus is speaking, "But what went ye out to see? A prophet? Yea, I say unto you, and much more than a prophet. This is he of whom it is written, Behold, I send my messenger before thy face, which shall prepare thy way before thee." He was referring to John the Baptist, God's messenger to prepare the way for Jesus' first coming.
The third instance was a young lady in the past century who was told that she was God's messenger. Selected Messages, book 1, pages 34 to 36: "If others call me by the name [prophet], I have no controversy with them. But my work has covered so many lines that I cannot call myself other than a messenger....My work includes much more than this name [prophet] signifies. I regard myself as a messenger, entrusted by the Lord with messages for His people."
