Matthew 10:11LXX

9Provide neither gold, nor silver, nor brass in your purses,

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.
