Notice the strong similarities between Pinchos and Dovid, and how both were loaded with Bizyonos. The Shevotim were M’vazeh Pinchos, since he descended from Yisro who fattened cows for Avoda Zara. (Rashi). Pinchos is Eliyahu (Medrash) and Achav called Eliyahu: עֹכֵר יִשְׂ רָאֵל מ"א יח יז one who brought misfortune on the Jewish nation, since he caused a drought for Klal Yisroel. This is especially difficult to accept; i.e., when a person is in the process of sticking up for Kavod Shamayim, and people tell him: "Who do you think you are, anyway!"
"You have a terrible background". "Mind your own business, and be happy we have anything to do with you!" "You have your own problems, so stay home and mind your own business". We find a striking similarity with Dovid. When he came to the battlefield and offered to kill Golyas HaPelishti, his older brother Eliav get angry at him for not staying home to mind his own business, and: "Do your job of taking care of the sheep".
