It is so entitled to this day. Sancheriv did not "jumble" it,35Sancheriv “jumbled” all the nations of the world by transporting the inhabitants of one country to another. (Yadayim, 4:3, Yeshaya, 10:13). He did the same to the inhabitants of Eretz Yisroel (Melachim 2, 17:6, 23, 24) but not to the inhabitants of Luz. and Nevuchadnetzar did not devastate it.36Sotah, 46:b.
