Matthew 10:11-13

Into whatsoever city, &c., ye shall enter, inquire who is worthy That you should abide with him, that is, who is of a good character, and disposed to receive the gospel. And there abide In that house, till ye leave the town. It is of much consequence that a preacher of the gospel should not endanger his reputation, by taking up his lodging in a disreputable family, or by removing from one family to another, out of regard to some little matter of domestic convenience or entertainment. This is more fully expressed in the instructions to the seventy, Luke 10:7.

“ In the same house remain, eating and drinking such things as they have: go not from house to house.” Doubtless the disciples on some occasions might change their quarters with decency; but our Lord absolutely forbade them to do it for the sake of better entertainment or accommodation, that they might not give mankind the least cause of imagining that they served their bellies, or were particularly solicitous about conveniences. When ye come into a house, salute it In the usual Jewish form, “Peace, (that is, all blessings,) be to this house.” If the house be worthy Of it, God shall give them the peace you wish them. If not, he shall give you what they refuse. The same will be the case when we pray for them that are not worthy.
