# let your peace return to you

Possible meanings are 1) if the household was not worthy, then God would hold back peace or blessings from that household or 2) if the household was not worthy, then the apostles were supposed to do something, such as asking God not to honor their greeting of peace. If your language has a similar meaning of taking back a greeting or its effects, that should be used here.
