Matthew 10:11-14
11Into whatever city or village you enter, find out who in it is worthy; and stay there until you go on. 12As you enter into the household, greet it. 13If the household is worthy, let your peace come on it, but if it isn’t worthy, let your peace return to you. 14Whoever doesn’t receive you, nor hear your words, as you go out of that house or that city, shake the dust off your feet. Matthew 10:11-14
