Anterooms are not subject to the law of ‘‘dwellings of idolaters.’’ R’ Shimon ben Gamliel says: The law of ‘‘dwellings of idolaters’’ does not apply to a city that was destroyed. East Kisrin and West Kisrin are graves. There was a doubt concerning East Ac-co, and the Sages declared it to be tahor. Rebbi and his Rabbinic court came to a vote on Keini and declared it tahor.
