2 “But you, Bethlehem Ephrathah,
though you are small among the clans of Judah,
out of you will come for me
one who will be ruler over Israel,
whose origins are from of old,
from ancient times.”
3 Therefore Israel will be abandoned
until the time when she who is in labor gives birth
and the rest of his brothers return
to join the Israelites.
4 He will stand and shepherd his flock
in the strength of the Lord,
in the majesty of the name of the Lord his God.
And they will live securely, for then his greatness
will reach to the ends of the earth.
5 And he will be their peace.
This is clearly one that gets cited in the Gospels as a messianic verse, but verses 4 and 5 don't get quoted along with it too often; they point to a more worldly king that is more of a real-time conquistador that the current mode of the King of Kings. That's why the Jews of the first century were a bit confused by Jesus, as they pictured more of a temporal king than a spiritual savior.
Either way, He is our peace, just not the shalom that they were expecting; that giant shalom comes later.
