시편 145:19의 Musar

Rashi explains (Brachos 33a) that when an arod (a poisonous reptile) or a snake bite a person, if the animal reaches water first, the person dies, and if the person reaches water first, the animal dies. Rabbi Yitzhak tells us that we may infer that the Holy One Blessed is He created a spring beneath Rabbi Chanina’s feet, in fulfillment of the verse, “He performs the will of those who fear Him and hears their cry and saves them.”
