Apocalypse of Moses 2

And after this, Adam and Eve were with one another and while they were sleeping, Eve said to Adam her lord: 'My lord, Adam, behold, I have seen in a dream this night the blood of my son Amilabes who is styled Abel being poured into the mouth of Cain his brother and he went on drinking it without pity. But he begged him to leave him a little of it. Yet he hearkened not to him, but gulped down the whole; nor did it stay in his stomach, but came out of his mouth. And Adam said, 'Let us arise and go and see what has happened to them. (I fear) lest the adversary may be assailing them somewhere.'
