Mark 6:9

7He called to himself the twelve, and began to send them out two by two; and he gave them authority over the unclean spirits.

8He commanded them that they should take nothing for their journey, except a staff only: no bread, no wallet, no money in their purse,

9but to wear sandals, and not put on two tunics.

10He said to them, “Wherever you enter into a house, stay there until you depart from there.

11Whoever will not receive you nor hear you, as you depart from there, shake off the dust that is under your feet for a testimony against them. Assuredly, I tell you, it will be more tolerable for Sodom and Gomorrah in the day of judgment than for that city!”
