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 had said above, The workman is worthy of his meat; that they should not hence suppose that He would open all doors to them, He here commands them to use much circumspection in the choice of a host, saying, Into what city or town ye enter, enquire who in it is worthy.
