Matthew 10:11-14
10:11 Whenever you enter a town or village, find out who is worthy there and stay with them until you leave.
10:12 As you enter the house, give it greetings.
10:13 And if the house is worthy, let your peace come on it, but if it is not worthy, let your peace return to you.
10:14 And if anyone will not welcome you or listen to your message, shake the dust off your feet as you leave that house or that town.
