Matthew 10:13-15

AUV(i) 13 And if the people seem trustworthy, express your wish for blessings to rest upon them. But if they prove to be untrustworthy, may those blessings remain on you [instead]. 14 And whoever does not welcome you or listen to what you have to say, shake the dust off of your shoes as you leave that house or town. [Note: This was a Jewish custom showing disdain and intended to suggest unworthiness] 15 It is true when I say to you, the districts around Sodom and Gomorrah [i.e., despite their gross sins] will be shown more leniency than that town on the day of judgment.
