Gênesis 4:1
Note that the name Cain means "ownership," which explains what was said at the time of his birth by his father or mother: "I have come into possession of a man through God." — City of God 15.17
Gênesis 4:2
Cain was followed by Abel, who was killed by his brother and served as the first prophetic symbol of the City of God. He was like an alien on earth, destined to suffer cruel persecutions at the hands of the wicked men who can properly be called natives of earth because they love this world as their home and find their happiness in the worldly felicity of the earthly city. — City of God 15.15
Gênesis 4:3-4
[The pagans say, "The Christians] censure the ceremonies of sacrifice, the victims, incense and the rest, which are used in temple worship. Yet the same ceremonies of sacrifice were originated by themselves or by the god they worship, in primitive times, when a god was assumed to need their offerings of first fruits." This question is evidently derived from that passage in our Scriptures that tells of Cain making an offering to God of the fruits of the earth and Abel of the firstlings of his flocks. We answer that the conclusion to be drawn from it is that sacrifice is a very ancient custom, because our true and sacred Books warn us that it is not to be offered except to the one true God. But God does not need sacrifices, as is most clearly expressed in the same sacred Books: "I said to the Lord, thou art my God, for thou hast no need of my goods," because in accepting or refusing or receiving them he is looking only to man's good. God does not derive any benefit from our worship, but we do. — LETTERS 102.3
Gênesis 4:17
Consider now the text: "And Cain knew his wife, and she conceived, and brought forth Enoch; and he built a city and called the name thereof by the name of his son Enoch." It does not at all follow from these words that we must believe Cain's first son was Enoch, as though "Cain knew his wife" must refer to their first intercourse. You have the same expression used of the first father, Adam, but not only in reference to the conception of Cain, who seems to have been his firstborn, since a little later Scripture records, "Adam knew his wife, and she conceived and brought forth a son and called his name Seth." — City of God 15.8
Gênesis 4:17
Now, it is recorded of Cain that he built a city, while Abel, as though he were merely a pilgrim on earth, built none. For the true city of the saints is in heaven, though here on earth it produces citizens in whom it wanders as on a pilgrimage through time looking for the kingdom of eternity. When that day comes, it will gather together all those who, rising in their bodies, shall have that kingdom given to them in which, along with their Prince, the King of Eternity, they shall reign forever and ever. — City of God 15.1
Gênesis 4:18-22
The text runs: "Methushael begot Lamech, who took two wives: the name of the one was Ada, and the name of the other Sella. And Ada brought forth Jobel; who was the father of such as dwell in tents, and of herdsmen. His brother's name was Jubal. He was the father of all those who play the psaltery and cittara. Sella bore Tobel; he was the forger of all instruments of bronze and iron. The sister of Tobel was Noema." This is as far as the line of descent from Cain is carried. There are eight generations in all, including Adam. The seventh is that of Lamech, who was the husband of two wives; the eighth is that of his children, among whom is the woman who is mentioned by name. What is here delicately intimated is that to the very end of its existence the earthly city will be propagated by physical births proceeding from the union of the sexes. This is why we are given the proper names of the wives of the last man mentioned as begetting children—a practice unheard of before the flood, except in the case of Eve. — City of God 15.17
Gênesis 4:25
It is quite possible that when Adam was divinely inspired to say, after Seth was born, "God has given me another seed, for Abel whom Cain slew," there is no implication here that Seth was the next born in the order of time but only that he was destined to be a fit heir in the order of holiness. — City of God 15.15
Gênesis 4:26
Seth means "resurrection," and the name of his son Enosh means "man." The name Adam also means "man," but in Hebrew it can be used for any human person, either male or female; as one can see from the text: "He created them male and female; and blessed them and called their name Adam." This text leaves no doubt that Eve was given her proper name, whereas the common noun "adam," or "human being," applied to both Adam and Eve. It was different with the name Enosh. This means "man," Hebrew scholars tell us, in the sense of a man as distinguished from a woman. Thus Enosh was a "son" of "resurrection." — City of God 15.17
Gênesis 4:26
We have two lines of succession, one descending from Cain and the other from the son who was born to Adam in order to be the heir of Abel who was killed and to whom Adam gave the name of Seth. He is referred to in the words "God has given me another seed, for Abel whom Cain slew." Thus it is that the two series of generations that are kept so distinct, the one from Seth and the other from Cain, symbolize the two cities with which I am dealing in this work, the heavenly city in exile on earth and the earthly city, whose only search and satisfaction are for and in the joys of earth. — City of God 15.15
