Matthew 10:9-14
9 Do not take along any gold or silver or copper in your belts;
10 take no bag for the journey, or extra tunic, or sandals or a staff; for the worker is worth his keep.
11 “Whatever town or village you enter, search for some worthy person there and stay at his house until you leave.
12 As you enter the home, give it your greeting.
13 If the home is deserving, let your peace rest on it; if it is not, let your peace return to you.
14 If anyone will not welcome you or listen to your words, shake the dust off your feet when you leave that home or town.
