Matthew 8
16 That evening they brought to him many who were oppressed by demons, and he cast out the spirits with a word and healed all who were sick.
17 This was to fulfill what was spoken by the prophet Isaiah: “He took our illnesses and bore our diseases.”
with a word
After relaying the Centurion's words in verse 8, "only say the word, and my servant will be healed," Matthew emphasizes again the power of Jesus to accomplish great things with just a word.
the prophet Isaiah
The quotation comes from the famous passage in Isaiah 53 about the Suffering Servant. Isaiah makes clear He always and only did us good, though we repaid Him with evil.
Isaiah 53:4
Surely he has borne our griefs
and carried our sorrows;
yet we esteemed him stricken,
smitten by God, and afflicted.
