Where did Cain get a wife? Who were Cain's son's?

One of the most puzzling questions in the Bible is where Cain, the firstborn son of Adam and Eve, found a wife. According to the book of Genesis, Cain killed his brother Abel out of jealousy, and was subsequently banished from the land where his parents and siblings lived. The text then states that Cain went to live in the land of Nod, where he knew his wife and had children.

So where did Cain's wife come from? There are a few different interpretations of this question, but one common explanation is that Cain's wife was one of his sisters. According to this theory, Adam and Eve had other children besides Cain, Abel, and Seth, and it is likely that Cain married one of his sisters. In the early days of human history, it was common for close relatives to marry, as there were no other people around.

It is also worth noting that the book of Genesis does not provide a lot of detail about Cain's wife or his children. We know that Cain and his wife had at least one son, named Enoch, and that Cain went on to found a city in the land of Nod. The text mentions other descendants of Cain, but does not provide much information about their lives or accomplishments.

Some scholars have suggested that the story of Cain and his descendants may be intended as a contrast to the story of Seth and his descendants, who are portrayed as more righteous and faithful. The book of Genesis presents Cain as a symbol of sin and rebellion, while Seth represents the line of righteous people who follow God's commands.
