But he was wounded for our transgressions. This verse contains four asseverations of the great truth that all Christ's sufferings were for us, and constituted the atonement for our sins. The form is varied, but the truth is one. Christ was "wounded" or "pierced"
The wounds inflicted by the nails caused his death, He was bruised; or, crushed (comp. Isaiah 3:15; Isaiah 19:10; Isaiah 57:15. Psalms 72:4). "No stronger expression could be found in Hebrew to denote severity of suffering—suffering unto death" (Urwick). The chastisement of our peace was upon him; i.e. "the chastisement which brought us peace," which put a stop to the enmity between fallen man and an offended God—which made them once more at one (comp. Ephesians 2:15-17, "Having abolished in his flesh the enmity, even the Law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace; and that he might reconcile both unto God in one body by the cross, having slain the enmity thereby: and came and preached peace to you which were afar off;" Colossians 1:20, "Having made peace through the blood of his cross, by him to reconcile all things unto himself"). With his stripes we are healed; rather, we were healed. Besides the blows inflicted on him with the hand (Matthew 26:27) and with the reed (Matthew 27:30), our Lord was judicially scourged (Matthew 27:26). Such scourging would leave the "stripe-marks" which are here spoken of.
