Luke 10:5-7

10:5 Whenever you enter a house, first say, ‘May peace be on this house!’ 10:6 And if a peace-loving person is there, your peace will remain on him, but if not, it will return to you. 10:7 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.
