Charles Ellicott Commentary Isaiah 53:5

"But he was wounded for our transgressions, he was bruised for our iniquities; the chastisement of our peace was upon him; and with his stripes we are healed." — Isaiah 53:5 (ASV)

He was wounded ... —Bruised. Both words refer to the death which crowned the sufferings of the Servant. That also was vicarious.

The chastisement of our peace — i.e., the punishment which leads to peace, that word including, as elsewhere, every form of blessing. (Compare to the reproof of life in Proverbs 15:31.) In Hebrews 2:10; Hebrews 5:8–9, we have the thought which is the complement of this, that the chastisement was also an essential condition of the perfection of the sufferer.

With his stripes we are healed. —The words stretch wide and deep. Perhaps the most touching application is St. Peter’s use of them as a thought of comfort for the slaves who were scourged as He, their Lord, had been (1 Peter 2:24).
