Question: Capernaum? Where is Capernaum?
Answer: Capernaum is in Galilee, in virtue of Luke 4:14-15:
Objection: Did the Gentile readers of canonical Luke know that Capernaum was in Galilee?
To my knowledge, the consensus says that Luke is a gospel addressed to gentiles. Gentiles are not obliged to know the geography of the Judea and Galilee. Even less to know a priori where Capernaum is.
Therefore: *Ev precedes Luke.
