Matthew 10:9-13

9 Don't take any gold, nor silver, nor brass in your money belts.  10 Take no bag for your journey, neither two coats, nor shoes, nor staff: for the laborer is worthy of his food.  11 Into whatever city or village you enter, find out who in it is worthy; and stay there until you go on.  12 As you enter into the household, greet it.  13 If the household is worthy, let your peace come on it, but if it isn't worthy, let your peace return to you.
