Shake the dust off when a place refuses the mission.

¹¹And 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.

⁵And 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.

¹⁰But into whatsoever city ye enter, and they receive you not, go your ways out into the streets of the same, and say,

¹¹Even the very dust of your city, which cleaveth on us, we do wipe off against you: notwithstanding be ye sure of this, that the kingdom of God is come nigh unto you.
