Mark 1

Peter’s mother-in-law

29 Immediately upon exiting the synagogue they went into the house of Simon and Andrew, with James and John. 30 Simon’s mother-in-law was lying down with a fever,*The parallel passage in Luke 4:37 specifies that it was a high fever—she was burning. The case mentioned in Matthew 8:14-15 is probably different, happening some time later. so without delay they told Him about her. 31 So He went and grasping her hand lifted her up; immediately the fever left her and she began to serve them.*A high fever usually leaves a person weak, even after it passes, so we really have a double miracle here: Jesus dismissed the fever, but also reversed its effect.
