And when Jesus was come into Peter's house. Straight from the synagogue (parallel passages), for food, Matthew 8:15 (Chrysostom). It seems clear, from the parallel passages, that St. Peter had not previously told our Lord about his mother-in-law's illness, but that he, with others, now asked ( ἠρώτησαν, Luke) him to heal her.
Among these others were probably Andrew, who also lived in the house, and James and John, who accompanied our Lord (Mark). Whether or not it was Peter's own house, we have no means of telling (but see next verse).
He saw. Presumably on entering, before they asked him about her. His wife's mother (1 Corinthians 9:5). As St. Peter lived for some forty years more, he can hardly have been now very long married (cf.
Bengel). Laid ( βεβλημένην); verse 6. And sick of a fever.
