Matthew 10:12KJV

10Nor scrip for journey, neither two coats, neither shoes, nor yet staves: for the workman is worthy of his meat.

11And into whatsoever city or town ye shall enter, enquire who in it is worthy; and there abide till ye go thence.

12And when ye come into an house, salute it.

13And if the house be worthy, let your peace come upon it: but if it be not worthy, let your peace return to you.

14And 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.
