Cyril of Alexandria : There is no association between the holy and the profane, between the pure and the impure. Those who belong to Christ are separated and refuse to mix with those who are in the world; they are free from carnal desires. They are marked by their way of life or rather are distinguished by their virtue. "The unmarked ones were Laban's, and the marked ones were Jacob's." — GLAPHYRA ON GENESIS, 5.4 John Chrysostom : The good man did this, not of his own devising but with grace from on high inspiring his mind. You see, it was not done according to human reasoning but was quite unusual and beyond natural logic. — HOMILIES ON Genesis 57.7
