Luke 10:5-8

Before you go into a house, say, ‘Peace be with this house.’ If peace-loving people live there, your blessing of peace will stay with them, but if not, then your blessing will come back to you. Stay in the same house, eating and drinking what the people there give you. A worker should be given his pay. Don’t move from house to house. If you go into a town and the people welcome you, eat what they give you.
