in this verse means,

Wounds from a whip,
rod, lash, strap,
or scourge
...Christ also suffered for us,
leaving us an example,
that ye should follow in His steps...
who His own self bare our sins in His own body on the tree,
that we, being dead to sins,
should live unto righteousness:
by whose stripes
ye were healed.

1 Peter 2:21, 24
