Two Swords

Why two swords in Luke 22: 38?  Those were the two swords that were carried by the two people on the road to Emmaus, later on in this Gospel.  They carried swords out of fear.  Their hopes had been dashed.  They were on their own, abandoned or abandoning the community back in Jerusalem.  Jesus came to them.  He opened the scriptures to them and gave them the Eucharist.  Word and sacrament mean that we have Jesus with us and do not need to protect ourselves with the sword.  Fear isolates and prevents us from proclaiming good news, or being good news for that matter.
