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

People's New Testament

8:17 Spoken by Isaiah. In the beautiful picture of the Messiah in Isa 53:1-12.

Wesley's Notes

8:17 Whereby was fulfilled what was spoken by the Prophet Isaiah - He spoke it in a more exalted sense. The evangelist here only alludes to those words, as being capable of this lower meaning also. Such instances are frequent in the sacred writings, and are elegancies rather than imperfections. 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. Isaiah 53:4.

Matthew Henry's Concise Commentary

8:14-17 Peter had a wife, yet was an apostle of Christ, who showed that he approved of the married state, by being thus kind to Peter's wife's relations. The church of Rome, which forbids ministers to marry, goes contrary to that apostle upon whom they rest so much. He had his wife's mother with him in his family, which is an example to be kind to our relations. In spiritual healing, the Scripture speaks the word, the Spirit gives the touch, touches the heart, touches the hand. Those who recover from fevers, commonly are weak and feeble some time after; but to show that this cure was above the power of nature, the woman was at once so well as to go about the business of the house. The miracles which Jesus did being noised abroad, many thronged to him. He healed all that were sick, though the patient was ever so mean, and the case ever so bad. Many are the diseases and calamities to which we are liable in the body; and there is more, in those words of the gospel, that Jesus Christ bore our sicknesses and carried our sorrows, to support and comfort us under them, than in all the writings of the philosophers. Let us not grudge labour, trouble, or expense in doing good to others.
