Matthew 10:12-18
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.
15 I tell you the truth, it will be more bearable for Sodom and Gomorrah on the day of judgment than for that town.
16 I am sending you out like sheep among wolves. Therefore be as shrewd as snakes and as innocent as doves.
17 “Be on your guard against men; they will hand you over to the local councils and flog you in their synagogues.
18 On my account you will be brought before governors and kings as witnesses to them and to the Gentiles.
