Matthew 10:14-16

And whoever will not receive you nor hear your words, when you depart from that house or city, shake off the dust from your feet. Assuredly, I say to you, it will be more tolerable for the land of Sodom and Gomorrah in the day of judgment than for that city! “Behold, I send you out as sheep in the midst of wolves. Therefore be wise as serpents and harmless as doves.
