What the Bible says about High Fever
(From Forerunner Commentary)
It is probable that Peter's wife's mother (likely a widow) was living with them. The family and their friends were quite concerned by her fever-stricken condition. Aware of the miracles Christ had begun to perform, they pleaded with Him to intervene on her behalf.
Yet, only Luke, a physician, adds the vital fact that she had a high fever. A doctor in Jesus' day would have noted the degree of fever to assess the severity of the patient's illness. Luke would have made careful inquiry into the details of the situation before recording his account. Thus, his testimony to the miraculous power of Christ is more reliable and thus of great importance, especially to new converts and skeptics.
