who his own self bore our sins in his body on the tree, that we, having died to sins, might live to righteousness; by whose stripes you were healed.
by whose stripes ye were healed: Isaiah 53 spoke of the "stripes" (molops) that would heal. Those bloody marks, laid across a person so numerous that they appeared as one, should have been ours; by His, though, we are healed. We are not healed of bodily afflictions (2 Corinthians 12:7) but rather of our sins so that salvation may be ours. What sin-wounds must be in souls that it required the death of Christ to heal us.
