Theophylact of Ohrid
Catena Aurea · Markusevangelium 1
And forthwith, when they were come out of the synagogue, they entered into the house of Simon and Andrew, with James and John. But Simon’s wife’s mother lay sick of a fever, and anon they tell him of her. And he came and took her by the hand, and lifted her up; and immediately the fever left her, and she ministered unto them.
He retired then as the custom was on the sabbath-day about evening to eat in His disciples’ house. But she who ought to have ministered was prevented by a fever. Wherefore it goes on, But Simon’s wife’s mother was lying sick of a fever.
