Luke 10:5-8

Whatever house you enter, first say, ‘Peace be to this house!’ And if a son of peace is there, your peace will rest upon him. But if not, it will return to you. And remain in the same house, eating and drinking what they provide, for the laborer deserves his wages. Do not go from house to house. Whenever you enter a town and they receive you, eat what is set before you.
