Luke 9:4

He pronounces it to be foreign to the character of a preacher of the heavenly kingdom to run from house to house and change the rights of inviolable hospitality; but as the grace of hospitality is supposed to be offered, so also if they are not received the dust must be shaken off, and they are commanded to depart from the city; as it follows, And whosoever will not receive you when ye go out of that city, shake off the very dust from your feet for a testimony, &c. Or it is a great return of hospitality which is here taught, i. e. that we should not only wish peace to our hosts, but also if any faults of earthly infirmity obscure them, they should be removed by receiving the footsteps of apostolical preaching.

But it may be said, How then shall necessary things be prepared for them. He therefore adds, And into whatsoever house ye enter, there abide, and thence depart. As if He said, Let the food of disciples suffice you, who receiving from you spiritual things, will minister unto you temporal. But He ordered them to abide in one house, so as neither to incommode the host, (that is, so as to send him away,) nor themselves to incur the suspicion of gluttony and wantonness.
