Shaking Out Yerushalayim

Chesed L'Avraham 1:17, R' Avraham Azulai, ztzvk"l (Free Translation)

Just like the verse in Yechezkiel states, that the Holy One blessed be He wants to shake out the land of Israel and Yerushalayim like a man shakes out his tallis, so will He shake out all the idoloters from Yerushalayim as well as the idolatry itself which is in Yerushalayim and the impure corpses which are buried around the holy place and all the filthy places in it.
