The paper discusses a number of the most remarkable responses to the COVID‑19 pandemic and to the social isolation measures coming from several, mostly ultra‑Orthodox, Jewish communities in Israel, the United States, and Russia. It examines major elements of the crisis discourse, i.e., the hermeneutics of the causes and meanings of the pandemic; the affirmation of group borders and hierarchies as a result of the search for culprits; the relations between the religious community and the state; as well as the possible transformations of social behavior and ritual practices resulting from the crisis.
