Matthew 10:11-16

“Whenever you enter a city or village, search for a worthy person and stay in his home until you leave town. When you enter the home, give it your blessing. If it turns out to be a worthy home, let your blessing stand; if it is not, take back the blessing. If any household or town refuses to welcome you or listen to your message, shake its dust from your feet as you leave. I tell you the truth, the wicked cities of Sodom and Gomorrah will be better off than such a town on the judgment day. “Look, I am sending you out as sheep among wolves. So be as shrewd as snakes and harmless as doves.
