Two by two

Mark 6:7-13 - Calling the Twelve to him, he sent them out two by two and gave them authority over evil 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 tunic. Whenever you enter a house, stay there until you leave that town. And if any place will not welcome you or listen to you, shake the dust off your feet when you leave, 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.

I wonder if any of the Twelve were surprised at Jesus' instructions. How long were they gone? What did Jesus do in the meantime? Probably more of the same things he had been doing -- preaching, healing, etc.

I wonder if any of the disciples' family members tagged along. It seems like they didn't, so maybe they weren't gone very many days. Though it does sound like each pair would go to more than one city or town.
