Let me break it down for you... I used the Strong's Concordance for a better understanding of each word.
"But he (Christ Jesus our Lord) was wounded (bore into, wedged/pried open) for our transgressions (rebellion), he was bruised (crumbled, broken
into crumbs/pieces) for our iniquities (perversity): the chastisement
(discipline/punishment) of our peace ["those punishments by which our
peace, our reconciliation with God, was to be purchased" (Wesley)] was
upon him; and with his stripes (blueness, weals, black and blue marks)
we are healed (mended by stitching, cured, repaired as if by a skilled
physician)." (Isaiah 53:5 KJV)
