Mark 6:7-12 NIV
Calling the Twelve to him, he began to send them out two by two and gave them authority over impure spirits. These were his instructions: “Take nothing for the journey except a staff—no bread, no bag, no money in your belts. Wear sandals but not an extra shirt. Whenever you enter a house, stay there until you leave that town. And if any place will not welcome you or listen to you, leave that place and shake the dust off your feet as a testimony against them.” They went out and preached that people should repent.
