Matthew 10:16

14 And whosoever shall not receive you, nor hear your words, when ye depart out of that house or city, shake off the dust of your feet.

15 Verily I say unto you, It shall be more tolerable for the land of Sodom and Gomorrha in the day of judgment, than for that city.

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 up to the councils, and they will scourge you in their synagogues;

18 And ye shall be brought before governors and kings for my sake, for a testimony against them and the Gentiles.

Do read the surrounding verses too, because the context often says more than a single verse.
