여호수아 15:49 미드라시: Sifrei Devarim

Similarly, (Joshua 15:49) "Danah and Kiryat Sanah — this is Dvir," and, elsewhere (Ibid. 15:15) "And the name of Dvir was formerly Kiryat Sefer" — whence it is found to have four names. Now why do future generations need to know this? (To impress upon them) that four kings were contending over it, each one saying "Let is be called by my name!" Now does this not follow a fortiori, viz.: If four kings contended over the "refuse" of Eretz Yisrael, how much more so is Eretz Yisrael (itself) to be lauded!
