Matthew 10:14

“As for them, whether they listen or whether they refuse—for they are a rebellious house—they will know that a prophet has been among them.

“And any place that does not receive you or listen to you, as you go out from there, shake the dust off the soles of your feet for a testimony against them.”

“Carry no money belt, no bag, no sandals, and greet no one on the way.

‘Even the dust of your city which clings to our feet we wipe off against you; yet know this, that the kingdom of God is at hand.’

But having shaken off the dust of their feet against them, they went to Iconium.
