Chapter 8:14-17 Peter's Mother-in-law and Many Others Healed

8:14 And when Jesus was come into Peter's house, He saw his wife's mother laid, and sick of a fever.
And when Jesus was come into Peter's house - And which was also Andrew's, for these two brothers lived together, and this was in Capernaum, as appears from the context.
and sick of a fever - Luke says, Luke 4:38 that she "was taken", or rather held, or "detained with a great fever"; the distemper was very raging and furious, it had got to a very great height.

8:15 And He touched her hand, and the fever left her: and she arose, and ministered unto them.

And He touched her hand -  Sometimes He healed by a word, as the centurion's servant; and sometimes by a touch, as here; and sometimes by both, as the leper. And she arose and ministered unto them - the former of these actions is a proof of her being restored to health and strength, in so much that she could rise and walk about of herself;

8:16 When the even was come, they brought unto Him many that were possessed with devils: and He cast out the spirits with His word, and healed all that were sick:

When the even was come - because the cool of the evening, and when the sun was set, it was more seasonable and convenient, in those hot countries, to bring out their sick, than in the heat of the day.

8:17 That it might be fulfilled which was spoken by Esaias the prophet, saying, Himself took our infirmities, and bare our sicknesses.

Whereby was fulfilled what was spoken by the Prophet Isaiah - He spoke it in a more exalted sense. He fulfilled these words in the highest sense, by bearing our sins in His own body on the tree: in a lower sense, by sympathizing with us in our sorrows, and healing us of the diseases which were the fruit of sin.
