Song of Solomon 7:8

The laurel and the palm are the symbols of victory. The heads of the victors are crowned with laurel, and the hand of the conqueror is adorned with a palm. Hence the Church says: "I said, I will go up to the palm tree, I will take hold of its branches." Seeing the excellence of the Word and hoping that she can ascend to His height and the summit of knowledge, she says: "I will go up to the palm tree," so that she may leave behind all lower things and strive for higher things, for the reward of Christ, so that she may enjoy and taste the sweet fruits of His love. For the fruit of virtue is sweet.

And thy breasts, etc. For truly, the first teachers of the Church, that is, the apostles, having completed His passion and resurrection, received a much greater knowledge of salvific doctrine than they had previously had, when appearing after the resurrection He opened their minds so that they might understand the Scriptures; when, having sent the Spirit from above, He granted them the knowledge of all languages; when it was falsely said by those mocking them that 'these men are full of new wine' (Acts 2). But they truly were like clusters of grapes because they were refreshed by the grace of spiritual gifts, the prophecy being verily fulfilled which said that new wine must be put into new bottles, and both are preserved (Matthew 9). And what follows aptly fits both senses:

And the smell of your breath is like apples, etc. Indeed, in the smell of the mouth is the fame of good speech, and in the throat, however, is the very duty of voice dedicated to God. Both are worthy of praise in the Catholic Church, and both in every elected soul, because the voice itself, which teaches those present, and the fame of speech, which reaches the absent, whether through letters or through those who have heard, is proven to be full of virtue and grace. But because he compares the smell of the bride's mouth and throat to apples and the best wine, it can be distinguished that apples retain all their strength in freshness itself, but wine achieves its value from age. Therefore, it is rightly compared to both these types—the voice of the Church speaking and its fame, whose beginning and perfection are known to be wonderful. Moreover, because the strength and fragrance of the best wine are greater than that of apples, it is rightly said: And the smell of your breath is like apples. Your throat is like the best wine, it surpasses the grace of apples. So much does the present speech of the holy Church of God excel the fame that the words of those who hear can spread about it. However, thus far the bride has been praised, and when it came to saying that her throat is like the best wine, she seized the word from the bridegroom's mouth, and she, led by great love, strives to complete it rather. For she understood that by the term "best wine" the word of the Gospel was designated, in which alone is eternal salvation for believers, and she said:
