Luke 10:5-7

Whatever house you enter, first say, ‘Peace [that is, a blessing of well-being and prosperity, the favor of God] to this house.’ And if anyone of peace is there [someone who is sweet-spirited and hospitable], your [blessing of] peace will rest on him; but if not, it will return to you. Stay in that house, eating and drinking what they provide, for the laborer is worthy of his wages. Do not move from house to house. [Deut 24:15]
