In a Baraita, Rabbi Jose related that a certain Elder from Jerusalem told him that 24 types of patients are afflicted with boils. The Gemara then related that Rabbi Joḥanan warned to be careful of the flies found on those afflicted with the disease "ra’atan", as flies carried the disease. Rabbi Zeira would not sit in a spot where the wind blew from the direction of someone afflicted with "ra’atan". Rabbi Elazar would not enter the tent of one afflicted with "ra’atan", and Rabbi Ami and Rabbi Asi would not eat eggs from an alley in which someone afflicted with "ra’atan" lived. Rabbi Joshua ben Levi, however, would attach himself to those afflicted with "ra’atan" and study Torah, saying this was justified by “The Torah is a loving hind and a graceful doe.” Rabbi Joshua reasoned that if Torah bestows grace on those who learn it, it could protect them from illness. When Rabbi Joshua ben Levi was on the verge of dying, the Gemara told, the Angel of Death was instructed to perform Rabbi Joshua’s bidding, as he was a righteous man and deserves to die in the manner he saw fit. Rabbi Joshua ben Levi asked the Angel of Death to show him his place in paradise, and the Angel agreed. Rabbi Joshua ben Levi asked the Angel to give him the knife that the Angel used to kill people, lest the Angel frighten him on the way, and the Angel gave it to him. When they arrived in paradise, the Angel lifted Rabbi Joshua so that he could see his place in paradise, and Rabbi Joshua jumped to the other side, escaping into paradise. Elijah the Prophet then told those in paradise to make way for Rabbi Joshua.
