Mark 6:8-12

and He instructed them that they were to take nothing for their journey, except a mere staff—no bread, no bag, no money in their belt—

but to wear sandals; and He added, “Do not wear two tunics.”

And He said to them, “Wherever you enter a house, stay there until you leave town.

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 as a testimony against them.”

And they went out and preached that people are to repent.
