Gregory the Dialogist : Behold, the Lord was not recognized while He was speaking, and He deigned to be recognized while He was being fed. Therefore, dearest brothers, love hospitality, love the works of charity. For hence it is said through Paul: "Let brotherly love continue in you, and do not forget hospitality. For through this some have pleased, having received angels as guests." Hence Peter says: "Be hospitable to one another without murmuring." Hence Truth itself says: "I was a stranger, and you took me in." — Forty Gospel Homilies, Homily 23 John Chrysostom : See how he enjoins them to preserve what they had: he does not add other things. He did not say, "Be loving as brethren," but, "Let brotherly love continue." And again, he did not say, "Be hospitable," as if they were not, but, "Be not forgetful of hospitality," for this was likely to happen owing to their afflictions. — Homily on Hebrews 33 Oecumenius : "Let brotherly love continue." Let it be unwavering, do not allow it to escape from you. — The Pseudo-Oecumenian Catena on Hebrews
