Mark 6:7-11

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

8He charged them to take nothing for their journey except a staff—no bread, no bag, no money in their belts—

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

10And he said to them, "Whenever you enter a house, stay there until you depart from there.

11And if any place will not receive you and they will not listen to you, when you leave, shake off the dust that is on your feet as a testimony against them."
