Matthew 10:11-15

And whatever city or village you enter, inquire who is worthy in it, and stay at his house until you leave that city. As you enter the house, give it your greeting. If the house is worthy, give it your blessing of peace. But if it is not worthy, take back your blessing of peace. Whoever does not receive you, nor heed your words, as you go out of that house or that city, shake the dust off your feet. Truly I say to you, it will be more tolerable for the land of Sodom and Gomorrah in the day of judgment than for that city.
