1 After this the Lord appointed seventy-two others and sent them on ahead of him two by two into every town and place where he himself was about to go. 2 He said to them, “The harvest is plentiful, but the workers are few. Therefore ask the Lord of the harvest to send out workers into his harvest. 3 Go! I am sending you out like lambs surrounded by wolves. 4 Do not carry a money bag, a traveler’s bag, or sandals, and greet no one on the road. 5 Whenever you enter a house, first say, ‘May peace be on this house!’ 6 And if a peace-loving person is there, your peace will remain on him, but if not, it will return to you. 7 Stay in that same house, eating and drinking what they give you, for the worker deserves his pay. Do not move around from house to house. 8 Whenever you enter a town and the people welcome you, eat what is set before you. 9 Heal the sick in that town and say to them, ‘The kingdom of God has come upon you!’ 10 But whenever you enter a town and the people do not welcome you, go into its streets and say, 11 ‘Even the dust of your town that clings to our feet we wipe off against you. Nevertheless know this: The kingdom of God has come.’ 12 I tell you, it will be more bearable on that day for Sodom than for that town!
The mishna teaches that Rabbi Yosei, son of Rabbi Yehuda, says: A laborer may not eat unless he performs labor with his hands and with his feet. The Gemara asks: What is the reasoning of Rabbi Yosei, son of Rabbi Yehuda? The Gemara explains: This halakha is like that of a threshing ox; just as one is not required to let an ox feed unless it is performing labor with its hands and with its feet, as it uses all four of its legs to thresh, so too a laborer is not entitled to eat unless he is performing labor with his hands and with his feet.
