Jesus sent to preach the good news

7And as ye go, preach, saying, The kingdom of heaven is at hand.

8Heal the sick, cleanse the lepers, raise the dead, cast out devils: freely ye have received, freely give.

9Provide neither gold, nor silver, nor brass in your purses,

10Nor scrip for your journey, neither two coats, neither shoes, nor yet staves: for the workman is worthy of his meat.

11And into whatsoever city or town ye shall enter, enquire who in it is worthy; and there abide till ye go thence.

12And when ye come into an house, salute it.

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, when ye depart out of that house or city, shake off the dust of your feet.

Note: They were sent to the lost sheep of Israel, not to the gentiles and neither the Samaritans. They Jews received the gospel first, by The Lord himself and with signs and miracles. Even thought, they rejected it. Because their rejection, we were called and invited to be part of this great salvation. But all of this was part of God's plan. It was prophetic.
