Greet a household when you enter it,
and if the household is worthy, let your peace be on it. But if it is unworthy, let your peace return to you.
If anyone will not welcome you or listen to your words, shake the dust off your feet when you leave that house or town.
I assure you: It will be more tolerable on the day of judgment for the land of Sodom and Gomorrah than for that town.
