Homilies on the Epistle to the Hebrews

“Let brotherly love continue. Be not forgetful of hospitality, for hereby some have entertained angels unawares.” 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.

Therefore (he says) “some have entertained angels unawares.” Do you see how great was the honor, how great the gain!

What is “unawares”? They entertained them without knowing it. Therefore the reward also was great, because he entertained them, not knowing that they were Angels. For if he had known it, it would have been nothing wonderful. Some say that he here alludes to Lot also.
