Theophylact of Ohrid, on Heb 12:16

“Lest there be any fornicator, or profane person, as Esau; who for one mess, sold his first birthright.”

“He does not say that Esau was a fornicator, but stop here: "lest there be any fornicator among you." For although he hints that some among them were vile, he does not wish to expose them, but feigns ignorance so that they might be corrected. Then again he said: "or profane person,... like Esau," that is, insatiable, worldly, one who defiles and tramples upon what is spiritual; for he gave away, and moreover for "one morsel of food," the privilege of the birthright given to him by God (Gen. 25). This is what "profaneness" is, namely contempt for what is divine. Here he shows them what an evil thing negligence is, because the elder, having fallen into faintheartedness and not having withstood the desire to eat, became the younger.”
