John Chrysostom
Catena Aurea · Matthäusevangelium 10
And into whatsoever city or town ye shall enter, enquire who in it is worthy; and there abide till ye go thence. And when ye come into an house, salute it. And if the house be worthy, let your peace eome upon it: but if it be not worthy, let your peace return to you. And whosoever shall not receive you, nor hear your words, when ye depart out of that house or eity, shake off the dust of your feet. Verily I say unto you, It shall be more tolerable for the land of Sodom and Gomorrha in the day of judgment, than for that city.
The Lord instructs them, that though they were teachers, yet they should not look to be first saluted by others; but that they should honour others by first saluting them. And then He shews them that they should give not a salutation only, but a benediction, when He says, If that house be worthy, your peace shall rest upon it.
