(Jesus continues to teach his disciples.)

Do you think that I came to bring peace on the earth?

This is a rhetorical question. People expected the Messiah to bring them peace from their enemies. This can be translated as "You should not think that I have come to bring peace on earth." (See: rc://en/ta/man/translate/figs-rquestion)

but rather division

"but I came to bring division"

division

"hostility" or "discord"

there will be five in one house divided

This is an example of the kind of division there will be even within families.
