These twelve Jesus sent out with the following instructions: “Go nowhere among the Gentiles, and enter no town of the Samaritans, but go rather to the lost sheep of the house of Israel. As you go, proclaim the good news, ‘The kingdom of heaven has come near.’ Cure the sick, raise the dead, cleanse the lepers, cast out demons. You received without payment; give without payment. Take no gold, or silver, or copper in your belts, no bag for your journey, or two tunics, or sandals, or a staff; for laborers deserve their food.
“See, I am sending you out like sheep into the midst of wolves; so be wise as serpents and innocent as doves. Beware of them, for they will hand you over to councils and flog you in their synagogues; and you will be dragged before governors and kings because of me, as a testimony to them and the Gentiles. When they hand you over, do not worry about how you are to speak or what you are to say; for what you are to say will be given to you at that time; for it is not you who speak, but the Spirit of your Father speaking through you.
Matthew 10:5-10, 16-20 (NRSV)
