John 1:21

New Catholic Bible

²¹Then they asked him, “Who then are you? Are you Elijah?”^[a] He said, “I am not.” “Are you the Prophet?” He answered, “No.”

John 1:21 Elijah: this prophet who had been carried away to heaven in a fiery chariot was expected to return to earth to announce the end time. The Prophet: i.e., the Prophet mentioned in Deut 18:15, 18, the one like Moses (see Acts 3:22), who was expected to be the Messiah and repeat the prodigies of the Exodus.
