The practice of some subsequent nations of permitting the royal families, supposedly descended from the gods, to marry brother to sister, dates from the traditions of the Adamic offspring — mating, as they must needs, with one another. The marriage ceremonies of the first and second generations of the Garden were always performed by Adam and Eve.

Cain left Yahweh’s presence, and lived in the land of Nod, east of Eden. Cain knew his wife. She conceived, and gave birth to Enoch. He built a city, and named the city after the name of his son, Enoch. Irad was born to Enoch. Irad became the father of Mehujael. Mehujael became the father of Methushael. Methushael became the father of Lamech. Lamech took two wives: the name of the first one was Adah, and the name of the second one was Zillah. Adah gave birth to Jabal, who was the father of those who dwell in tents and have livestock. His brother’s name was Jubal, who was the father of all who handle the harp and pipe. Zillah also gave birth to Tubal Cain, the forger of every cutting instrument of bronze and iron. Tubal Cain’s sister was Naamah. Lamech said to his wives, “Adah and Zillah, hear my voice. You wives of Lamech, listen to my speech, for I have slain a man for wounding me, a young man for bruising me.
If brothers dwell together, and one of them dies and has no son, the wife of the dead shall not be married outside to a stranger. Her husband’s brother shall go in to her, and take her as his wife, and perform the duty of a husband’s brother to her. It shall be that the firstborn whom she bears shall succeed in the name of his brother who is dead, that his name not be blotted out of Israel.
The man knew Eve his wife. She conceived, and gave birth to Cain, and said, “I have gotten a man with Yahweh’s help.” Again she gave birth, to Cain’s brother Abel. Abel was a keeper of sheep, but Cain was a tiller of the ground. As time passed, Cain brought an offering to Yahweh from the fruit of the ground. Abel also brought some of the firstborn of his flock and of its fat. Yahweh respected Abel and his offering, but he didn’t respect Cain and his offering. Cain was very angry, and the expression on his face fell. Yahweh said to Cain, “Why are you angry? Why has the expression of your face fallen? If you do well, won’t it be lifted up? If you don’t do well, sin crouches at the door. Its desire is for you, but you are to rule over it.” Cain said to Abel, his brother, “Let’s go into the field.” While they were in the field, Cain rose up against Abel, his brother, and killed him.
