Genesis 4:17

circ. 3875 Cain knew his wife; of which phrase See Poole on "Genesis 4:1". He built a city; partly to divert his troubled mind with business and pleasure, and partly for his own security against the enemies and evils which his guilty conscience made him fear, notwithstanding the assurance which God had given him. And this he did as soon as he was in capacity for it, either by the increase of his own posterity, or by the accession of other degenerate sons of Adam to him, who either being banished, or having departed from the church, willingly associated themselves with their brethren in iniquity. After the name of his son, Enoch; not after his own name, which he knew to be infamous and hateful.
