The Book of the Cave of Treasures 19

1And Yaréd his son rose up and ministered before God [in the Cave of Treasures]. He was a perfect man, and was complete in all the virtues, and he was constant in prayer by day and by night. And because of the excellence of his life and conversation, his days were longer than those of all the children of his people. And in the days of Yaréd, in the five hundredth year of his life, the children of Seth broke the oaths which their fathers had made them to swear. And they began to go down from that holy mountain to the encampment of iniquity of the children of Cain, the murderer, and in this way the fall of the children of Seth took place.

2AND IN THE FORTIETH YEAR OF YARED THE FIRST THOUSAND YEARS, FROM ADAM TO YARED, CAME TO AN END.

3And in these years the handicraftsmen of sin, and the disciples of Satan, appeared, for he was their teacher, and he entered in and dwelt in them, and he poured into them the spirit of the operation of error, through which the fall of the children of Seth was to take place.
