Matthew 10:11-16

Whatever town or village you enter, search there for some worthy person and stay at their house until you leave. As you enter the home, give it your greeting. If the home is deserving, let your peace rest on it; if it is not, let your peace return to you. If anyone will not welcome you or listen to your words, leave that home or town and shake the dust off your feet. Truly I tell you, it will be more bearable for Sodom and Gomorrah on the day of judgment than for that town.

“I am sending you out like sheep among wolves. Therefore be as shrewd as snakes and as innocent as doves.
