Ambrose of Milan : Therefore, Isaac is a true blessing, full of grace, and a source of joy. To this source, Rebecca came to fill her water jug. For the Scripture says that as she went down to the spring, she filled her jug and went up again (Gen. XXIV, 16). So she went down to the fountain of wisdom, whether the Church or the soul, to fill her entire vessel and to draw from the pure disciplines of wisdom that the Jews refused to draw from the flowing fountain. Who is this fountain, listen to the one saying: They have abandoned me, the fountain of living water (Jeremiah II, 13). To this fountain ran the thirsting soul of the prophets, as David also says: My soul thirsts for the living God (Psalm XLI, 3); so that it could quench its thirst with the richness of divine knowledge and wash away the blood of foolishness with the flow of spiritual waters. — On Isaac and the Soul Origen of Alexandria : Nor was this written about her in vain. Yet it moves me, what is meant by what is said: "She was a virgin, a virgin, no man had known her," as though a virgin were anything other than one whom no man has touched. And what does the addition in the case of a virgin seem to mean, that it should be said that "no man had known her"? For is there some virgin whom a man has touched? I have already often said that in these things histories are not narrated, but mysteries are woven together. I think, therefore, that something of this sort is indicated here. Just as Christ is called the husband of the soul, to whom the soul is wedded when it comes to faith, so too there is that husband contrary to him, to whom the soul is wedded when it turns aside to faithlessness — that very one who is also called "the hostile man," when he "sows tares over the wheat." It is not enough, therefore, for the soul to be chaste in body; it is necessary that this most wicked husband also "has not known her." For it can happen that someone has virginity in the body and yet, knowing that most wicked husband the devil and receiving from him the darts of concupiscence in the heart, has lost the chastity of the soul. Because, therefore, Rebekah was a holy virgin in body and spirit, on that account it doubles her praise and says: "She was a virgin, no man had known her." — HOMILIES ON Genesis 10.4
