Passage
And he touched her hand, and the fever left her: and she arose, and ministered unto them.
And he touched her hand, and the fever left her: and she arose, and ministered unto them.
Matthew 8:13 And Jesus said unto the centurion, Go thy way; and as thou hast believed, so be it done unto thee. And his servant was healed in the selfsame hour.
Matthew 8:14 And when Jesus was come into Peter’s house, he saw his wife’s mother laid, and sick of a fever.
Matthew 8:15 And he touched her hand, and the fever left her: and she arose, and ministered unto them.
Matthew 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:
Matthew 8:17 That it might be fulfilled which was spoken by Esaias the prophet, saying, Himself took our infirmities, and bare our sicknesses.
The verse centers on "touched", "hand", "fever", "left", "arose", and "ministered". It is saying that the verse draws attention to "touched" and "hand", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 14's "And when Jesus was come into Peter..." into verse 16's "When the even was come they brought...", so "touched" and "hand" belong inside that flow. In Matthew context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "touched" and "hand" with trust shaped by these words, not by a vague optimism outside the passage.
