The murder of Abel in The Book of the Rolls:
"When a hundred years had passed over him after his exile from Paradise, and he and Eve were grieved and weeping, they went down from the holy hill to its foot, and there Adam knew Eve, and she conceived, and her time was fulfilled, and she bare Cain, and Lusia his twin-sister. He knew her again, and she conceived, and her time was fulfilled, and she bare Abel and also his twin-sister Aclima. The boys and the girls grew, and attained to discretion. Adam said to Eve,
If God lets these lads and lasses grow up, let Cain marry Aclima the sister of Abel, and let Abel marry Lusia the sister of Cain.And they did thus. But Cain said to Eve,
O Mother, I have a greater right to my sister who was born with me. Let her be given to me as a wife, and let Abel’s sister who was born with him be given to him as a wife.For Lusia was more beautiful than Aclima, being like her mother Eve. Adam heard of his speech, and it made him angry and annoyed him.
He said to Cain, his son,
Thy request, O my son, is unlawful, for it is not allowed to thee to marry thy sister who was born with thee.From that time Cain envied his brother Abel and thought of killing him. Then Adam said to him and to Abel,
Choose some of the fruits of the earth and of the young of the flock and go up this holy hill, and go into the Cave of Treasures, and pray there before the Lord. Offer to Him what you have brought, fruit, and any young animals as an offering. When you have done this, let each of you take his wife.And they did so;
While they were going up the hill, behold! the Devil entered into Cain, and incited him to the murder of Abel.Then they brought their offerings before the Lord; the Lord accepted the offering of Abel and rejected the offering of Cain, because God, may He be praised and exalted! knew the purpose of Cain, and how he was preparing the murder of his brother.
When Cain saw that the Lord, may His name be praised! had accepted the offering of Abel instead of his offering, his envy of Abel increased and his wrath against him. When they came down from the hill, Cain attacked Abel and slew him with a sharp stone. God cursed Cain, and his decree came down against him. He did not cease to be in fear and terror all the days of his life. God led him with his wife from the holy hill, outside to the cursed land [of Nod], and they lived there [in exile].Adam and Eve grieved much about Abel for a hundred years. Then Adam came near to Eve, and she conceived, and her time was fulfilled, and she bare Seth, the handsome man, the complete and perfect giant. In his perfection he was like his father Adam, and God protected him when he grew up, making him the father of the other giants of the earth. The first who was born to Seth was Enos. And Enos begat Cainan, and Cainan begat Mahlaleel; these were born during the life of Adam. Adam lived nine hundred and thirty years, to the time that Mahlaleel was a hundred and thirty-five years old. When the time of his death came, he summoned Seth, and Enos, and Cainan and Mahlaleel; he prayed over them and blessed them, and commanded to his son Seth this Testament."
Also From The Book of the Rolls:
"Lamech the Blind, of the tribe of Cain the murderer, killed [some one] in the thicket known as Nod. This was the cause of it. Lamech was passing the thicket, leaning upon one of his youthful sons. He heard a movement in the thicket, it was the movement of Cain, for it was not possible for him to stay in one place since he had killed his brother. Lamech thought that this movement was that of some wild beasts. He took up a stone from the ground and threw it towards the moving thing. The stone hit Cain between the eyes and killed him."
From Land of the Lion and the Sun:
"One day Cain saw Satan killing a raven with a pointed black pebble. Cain picked up the stone and cut the throat of his brother with it, and then washed his hands. But the stain was still on his hands, even when he had washed his hands day after day. And so long as Cain lived, he was never able to get rid of the blood of his brother from his hands."
From Origen of Alexandria:
"Let us interject something of a mystery, which is said concerning the sinner Cain, who 'having gone out from the face of God, lived in the land of Nod opposite Eden.' 'Nod' in the Greek language means trembling. Whoever indeed forsakes God, who abandons understanding, whose thinking is continually 'in the land of Nod' dwells there today also, that is, that person remains in wicked unsettlement of heart and in commotion of mind."
