Mattityahu 10:13-15

Orthodox Jewish Bible

¹³ And if indeed the bais is a bais chayil (a house of worthiness), let your shalom come upon it; but if it is not a bais chayil, let your shalom return to you.

¹⁴ And whoever neither receives you nor listens to your divrei [Moshiach], as you are leaving and as you go outside of that bais (house) or city, then let it be NIER CHATZNO (shake out the fold of the robe, i.e., wash ones hands of), shake off the dust of your feet.

¹⁵ Omein, I say to you, it will be more tolerable on Yom HaDin (the Day of Judgment) for Sdom and Amora than for that shtetl.
