Jesus said, “And preach as you go, saying, ‘The kingdom of heaven is at hand.’ Heal the sick, raise the dead, cleanse lepers, cast out demons. You received without pay, give without pay. Take no gold, nor silver, nor copper in your belts, no bag for your journey, nor two tunics, nor sandals, nor a staff; for the labourer deserves his food. And whatever town or village you enter, find out who is worthy in it, and stay with him until you depart. As you enter the house, salute it. And if the house is worthy, let your peace come upon it; but if it is not worthy, let your peace return to you.
