The First Book of Adam and Eve 76
5Then Adam told him all that had befallen them. And Abel felt deeply about what his father told him.
6Furthermore his father Adam, told him of the works of God, and of the garden; and after that, he remained behind his father the whole of that night in the Cave of Treasures.
8But as for Abel, he prayed to God, and drove away Satan from him; and believed not the words of the devil. Then when it was day, an angel of God appeared unto him, who said to him, "Shorten neither fasting, prayer, nor offering up an oblation unto thy God. For, lo, the Lord has accepted thy prayer. Be not afraid of the figure which appeared unto thee in the night, and who cursed thee unto death." And the angel departed from him.
9Then when it was day, Abel came to Adam and Eve, and told them of the vision he had seen. But when they heard it, they grieved much over it, yet said nothing to him about it; they only comforted him.
10But as to hard-hearted Cain, Satan came to him by night, showed himself and said unto him, "Since Adam and Eve love thy brother Abel much more than they love thee, and wish to join him in marriage to thy beautiful sister, because they love him; but wish to join thee in marriage to his ill-favoured sister, because they hate thee;
11"Now, therefore, I counsel thee, when they do that, to kill thy brother; then thy sister will be left for thee; and his sister will be cast, away."
12And Satan departed from him. But the wicked One remained behind in the heart of Cain, who sought many a time, to kill his brother.
