The Second Book of Adam and Eve 11
4But because of their own purity, they were named "Children of God," and they were with God, instead of the hosts of angels who fell; for they continued in praises to God, and in singing psalms unto Him, in their cave--the Cave of Treasures.

6But Seth and his children did not like earthly work, but gave themselves to heavenly things; for they had no other thought than praises, doxologies, and psalms unto God.
7Therefore did they at all times hear the voices of angels, praising and glorifying God; from within the garden, or when they were sent by God on an errand, or when they were going up to heaven.
8For Seth and his children, by reason of their own purity, heard and saw those angels. Then, again, the garden was not far above them, but only some fifteen spiritual cubits.
9Now one spiritual cubit answers to three cubits of man, altogether forty-five cubits.
11Then Seth often fasted every forty days, as did also his eldest children. For the family of Seth smelled the smell of the trees in the garden, when the wind blew that way.
12They were happy, innocent, without sudden fear, there was no jealousy, no evil action, no hatred among them. There was no animal passion; from no mouth among them went forth either foul words or curse; neither evil counsel nor fraud. For the men of that time never swore, but under hard circumstances, when men must swear, they swore by the blood of Abel the just.
14And they did so until the end of Seth drew near.
