In Psalm 91, the psalmist implores Jews not to become overwhelmed by fear, promising that God will protect and deliver the faithful from the troubles that threaten them. Foremost among these, as laid out in verse 6, are “pestilences” and “plagues.” Reciting or praying this psalm and this verse has been used for centuries as a way for Jews to remain hopeful in the face of challenges, especially during times of pandemic disease. This paper details how the rabbinic literature understood Psalm 91:6 as a description of a demonic force, and describes how Jews were told to protect themselves from this force, namely through faith and trust in God and through religious observance. The paper also discusses the Jewish experience with pestilential disease, from the 14th century plague pandemic to the 19th century cholera pandemics to the 1918 influenza pandemic and to the recent COVID-19 pandemic. Finally, the paper lays out how Jews have made use of Psalm 91:6 in responding to the threat of pandemics, especially during COVID-19, including through both prayer and more esoteric applications.
