Luke 10:5-8

But whatever house you enter, first say, ‘Peace to this house.’ And if a son of peace is there, your peace will rest on it; if not, it will return to you. And remain in the same house, eating and drinking such things as they give, for the laborer is worthy of his wages. Do not go from house to house. Whatever city you enter, and they receive you, eat such things as are set before you.
