Eretz Pelishtim was near Egypt (Shemos 13:17, Yehoshua 13:3), southeast of Eretz Yisrael. Dan was in the north! Rashi (Yehoshua 19:41) - Dan initially received near Yehudah (Malbim - west of Binyamin), and later conquered Leshem in the north. Rashi (Devarim 33:22) says that initially, Dan received in the northwest! Perhaps he means northwest of Yehudah (refer to Yehoshua 19:41:1:2). (PF)
