A "prophet" is not primarily someone who "predicts" the future, but rather is a chosen
messenger or representative of God, whose role is to speak God’s words and to perform some
miraculous and/or symbolic actions for the people to see.

OT: The most important early prophets are Elijah and Elisha (1 Kings 16 - 2 Kings 9), who both
perform many miracles. The four major prophetic books are attributed to Isaiah, Jeremiah,
Ezekiel, and Daniel. The OT also promises that "a prophet like Moses" will appear (Deut
18:15-18) and/or the prophet "Elijah will return" (Mal 4:5-6) in the last days.

NT: The OT prophets often mentioned and quoted, esp. in Matthew. Both John the Baptist and
Jesus are appropriately considered "prophets," because of their speech and actions, even though
they have very different styles. In the Synoptics, Jesus says that John the Baptist was a prophet
and compares him to Elijah (Mt 11:7-19; Lk 7:24-35), but in the Fourth Gospel, John the Baptist
himself disputes that he was the Elijah-figure people were expecting (Jn 1:19-23). Jesus is also
considered a great prophet by many people (Mk 6:14-16; 8:28; Mt 21:11; Lk 7:16; 24:19; Jn
6:14; etc.).
