Matthew 10:11-21

11 And into whatever city or town ye shall enter, inquire who in it is worthy, and there abide till ye go thence.
12 And when ye come into a house, salute it.
13 And if the house be worthy, let your peace come upon it: but if it be not worthy, let your peace return to you.
14 And whoever shall not receive you, nor hear your words, when ye depart from that house, or city, shake off the dust of your feet.
15 Verily, I say to you, It shall be more tolerable for the land of Sodom and Gomorrah, in the day of judgment, than for that city.
16 Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves.
17 But beware of men: for they will deliver you to the councils, and they will scourge you in their synagogues.
18 And ye will be brought before governors and kings for my sake, for a testimony against them and the Gentiles.
19 But when they deliver you up, be not anxious how or what ye shall speak, for it shall be given to you in that same hour what ye shall speak.
20 For it is not ye that speak, but the Spirit of your Father which speaketh in you.
21 And the brother will deliver up the brother to death, and the father the child: and the children will rise up against [their] parents, and cause them to be put to death.
