Bede

I was almost in all evil, etc. The Church and the Synagogue are Greek names, and they signify the same thing in Latin, that is, an assembly of many together. But if they are distinguished more subtly, the Church is interpreted as a calling together, the Synagogue as a gathering together. And indeed the old people of God were called by both names. Now, however, for the sake of distinction, that one is called the Synagogue, ours is called the Church, rightfully indeed because of the greater faith and knowledge, because even irrational creatures can be gathered. Finally, God said, Let the waters be gathered into one gathering. Only the rational and sensible can be called together. But these names sometimes signify the gathering of the wicked. Hence that, "Fire burned their assembly" (Psalm 105); and, "I hated the assembly of evildoers" (Psalm 26). Therefore, what the late penitent, contemptuous of wisdom, says, "I was almost in all evil, in the midst of the congregation and assembly," seems to refer to someone sadly recognizing the magnitude of his own damnation, because he was involved in almost every sin, worthy of undergoing such torments. This adds to the heap of his miseries, that he was not merely the last of sinners, but rather in the midst and almost the leader. Or indeed, placed bodily in the midst of holy assemblies, he did not fear to lead a different life from them. And this is particularly felt about heretics because they could not be recalled from error by the sayings and examples of either the ancient fathers or the new ones.

"Let her breasts satisfy you at all times," etc. He does not teach that one should always be occupied with conjugal work, but advises not to marry another while the first wife is alive, or ever associate with a prostitute. Otherwise, what he says, "Drink water from your own cistern and flowing water from your own well," teaches that one should beware of heretics and attend to the custody of the Scriptures and reading. Keep the knowledge, he says, that you preach to others, and the watering of your speech pours out. "Let your fountains be dispersed abroad, and divide your waters in the streets." When you have kept it yourself, then also preach to others, and in the great multitude of listeners, dispense divine words according to each one's quality. "Let them be yours alone." We divide the waters in the streets and yet possess them alone, when we also broadly spread the preaching outwardly, and yet by it we do not aim to achieve human praises. "And let strangers not share with you." Unclean spirits become the teacher's partners if they corrupt his mind with pride while he preaches, or with heresy, or any other vice. But alone he possesses the waters when faithfully connected with the Church's members, he keeps himself free from the company of strangers. "Let your fountain be blessed, and rejoice with the wife of your youth." Let your doctrine be, and whoever is born from it, in the blessing of the Church, and rejoice with her to whom you have been joined from youth, that is, from the first time of believing. "A loving doe, a graceful fawn; let her breasts satisfy you at all times, and always be enraptured with her love." The most beloved or most pleasing deer, as some manuscripts have it, is the holy Church, which is accustomed to hate and crush the serpent-like doctrine. The most pleasing young stag is the people, delightful by the variety of its virtues, and always kindled by the emulation of the same pure faith. We are intoxicated by its breasts, when we are instructed by the pages of both Testaments against the deceptions of heretics. To always delight in its peace and love is a great occasion for exercising virtues.
