Matthew 10:12

And when ye come into an house
Or the "house"; that is, the house of an hospitable man, when, upon inquiry, found out:

meaning the inhabitants of it; or, as the Persic version reads, those of the household, especially the master of the family. Some copies add, saying, peace be to this house, as in ( Luke 10:5 ) and so read the Vulgate Latin, and Munster's Hebrew Gospel; and is a very just, and proper explanation of saluting: for the usual form of salutation among the Jews was in such words; of which (See Gill on Matthew 5:47) by which is meant all kind of happiness, and prosperity, temporal, spiritual, and eternal.
