Do you not know that a prince and a great man has fallen this day in Israel?

This rhetorical question is used to show how much David respected Abner. Here "fallen" is a euphemism that means "died." It can be translated as a statement. Alternate translation: "It is certainly true that a great prince has died today in Israel!" (See: rc://en/ta/man/jit/figs-rquestion and rc://en/ta/man/jit/figs-euphemism)

a prince and a great man

These two phrases both refer to Abner. Alternate translation: "a great prince" (See: rc://en/ta/man/jit/figs-hendiadys)
