Matthew 10:13-18

13And if the house be worthy, let your peace come upon it: but if it be not worthy, let your peace return to you. 14And whosoever shall not receive you, nor hear your words, as ye go forth out of that house or that city, shake off the dust of your feet. 15Verily I say unto you, It shall be more tolerable for the land of Sodom and Gomorrah in the day of judgment, than for that city.

16Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves. 17But beware of men: for they will deliver you up to councils, and in their synagogues they will scourge you; 18yea and before governors and kings shall ye be brought for my sake, for a testimony to them and to the Gentiles.
