Rada"l on Tadmor
"This is Tarmud" - this is Tadmor in the desert among the cities that Shelomo built. And it is on the opening of an Arabian desert where Arabs and Yishmaelites reside. And this is why it says about them the gate of his enemies. As it says in Pirkei DeRibbi Eliezer at the end of chapter 28 and chapter 48 that אויביו ["his enemies"] refers to Yishmael.Apparently, it needs to be destroyed by ISIS first, as per the gemara Yevamot and Midrash Eicha Rabbati/Yerushalmi Ta'anit. Only afterwards will it be inherited by the Jewish people, Bimhera Veyameinu, Amen.
