MSB(i)
5 Whatever house you enter, begin by saying, ‘Peace to this house.’
6 If a man of peace is there, your peace will rest on him; if not, it will return to you.
7 Stay at the same house, eating and drinking whatever you are offered. For the worker is worthy of his wages. Do not move around from house to house.
8 If you enter a town and they welcome you, eat whatever is set before you.
