Matthew 10:12

10Take no bag for your journey, neither two coats, nor sandals, nor staff: for the laborer is worthy of his food.

11Into whatever city or village you enter, find out who in it is worthy, and stay there until you go on.

12As you enter into the household, greet it.

13If the household is worthy, let your peace come on it, but if it isn’t worthy, let your peace return to you.

14Whoever doesn’t receive you or hear your words, as you go out of that house or that city, shake the dust off your feet.
