Mark 6:6-13 NIV
He was amazed at their lack of faith. Then Jesus went around teaching from village to village. 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. They drove out many demons and anointed many sick people with oil and healed them.
