Song of Solomon 4:13

"Pomegranate" is to be taken figuratively as love, since countless seeds are contained together within the one skin, pressed together without squeezing or ruining one another, remaining fresh unless one of the seeds in the middle goes bad. You can also gain a different insight from the sections in the middle: we see many ranks also among the saved, one of virgins, one of ascetics, one of those drawing the yoke of marriage, and of the affluent, one of those living a life of poverty, one of slaves in love with godliness, one of masters exercising lordship lawfully. The pomegranate, too, then, has walled off compartments, as it were, separating its seeds into certain divisions. This is the reason he compares the presents of the bride to "an orchard of pomegranates."

In order that we may know the plants that the Word cultivates in believers, the Song calls the trees he planted "pomegranates." These issue from the bride's mouth. The pomegranate is difficult for a thief to grasp because of its thorny branches, and its fruit is surrounded and protected by a rind bitter and harsh to the taste. Once the pomegranate ripens in its own good time, and once the rind is peeled off and the inside revealed, it is sweet and appealing to the sight much like honey to the taste; its juice tastes like wine and affords much pleasure to the palate. I think that the issues from the bride's mouth [are] a "garden of pomegranates" present in the souls of those listening to her. We must heed her words and not become soft by indulgence and enjoyment of this present life. Rather we should choose a life that has become toughened by continence. Thus virtue's fruit is inaccessible to thieves and is protected by the bitter covering of self-control. Surrounded by a solemn, austere way of life, it wards off as though by spiny thorns those who approach the fruit with evil intent.

Your branches are a paradise of pomegranates, etc. Because the early Church, which was at Jerusalem, produced many people for God from water and the Spirit, it is rightly said that the sacred garden, assisted by the irrigation of the divine fountain, emitted a paradise, not of any kind of trees, but of pomegranates with the fruits of apples. The pomegranates, which bloom with a blood-red color, signify the triumphs of those in the Church who, after the general washing of the sealing fountain, are also baptized with their own blood. However, the fruits of the apples indicate the works of general virtues, or those who perform the works of virtues: although among the pomegranates, which this garden is first said to emit from itself, the whole assembly of the baptized can rightly be accepted, because undoubtedly the regenerating fountain is dedicated to the mystery of the Lord's passion. For as many of us as were baptized in Christ Jesus, were baptized into His death. For we were buried with Him by baptism into death, so that just as Christ rose from the dead by the glory of God, we also might walk in newness of life (Rom. VI). However, after the many pomegranates, follow the fruits of apples and spices, worthy of such a beginning, because after the ascent of the fountain sprinkled with His precious blood, through which we become the children of God, it necessarily follows that the fragrant fertility of virtues, with which the grace of our regeneration is adorned and always grows, comes.
