The Scriptures are clear on this matter:
And whosoever shall not receive you, nor hear your words, when ye depart out of that house or city, shake off the dust of your feet. Mat 10:14
And whosoever shall not receive you, nor hear you, when ye depart thence, shake off the dust under your feet for a testimony against them. Verily I say unto you, It shall be more tolerable for Sodom and Gomorrha in the day of judgment, than for that city. Mark 6:11
And whosoever will not receive you, when ye go out of that city, shake off the very dust from your feet for a testimony against them. Luke 9:5
