Matthew 10:10-14

Nor scrip for your journey, neither two coats, neither shoes, nor yet staves: for the workman is worthy of his meat.

And into whatsoever city or town ye shall enter, enquire who in it is worthy; and there abide till ye go thence.

And when ye come into an house, salute it.

And if the house be worthy, let your peace come upon it: but if it be not worthy, let your peace return to you.

And whosoever shall not receive you, nor hear your words, when ye depart out of that house or city, shake off the dust of your feet.
