jesus select seventy disciples and sent them two by two go to every city and place. jesus told them: "the harvest is indeed a lot but the laborers are few, so ask the Lord of the harvest, so that he send out the laborers to harvest it. go, truely, I send you out as lambs among wolves. do not carry purses, wallet, or shoes, and do not greet anyone during your trip. if you enter a house, first say: peace will be in this house. and if there are people who deserve peace, then your greet will stay above them. but if not, your greet will back to you. stay in that house, eat and drink what people given to you, because a worker deserves his wages. and if you go into a town and you are accepted there, eat what is served to you, and heal the sick who were there and say to them: the kingdom of God is near. but if you go into a town and you're not accepted in there, then shake the dust at your feet in front of that people, and told them: the kingdom of God is near. I say to you, later that city will receive a very severe punishment."
