John Chrysostom, on Heb 13:1

“Let the charity of the brotherhood abide in you.”

“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.”
