"Adam was the first...."
AND when they had ended their prayer, the Word of God came and comforted them concerning their father Adam.
2 After this, they offered their gifts for themselves and for their father.
3 And when they had ended their offering, the Word of God came to Seth, the eldest among them, saying unto him, "O Seth, Seth, Seth, three times. As I was with thy father, so also shall I be with thee, until the fulfilment of the promise I made him-thy father saying, I will send My Word and save thee and thy seed.
4 But as to thy father Adam, keep thou the commandment he gave thee; and sever thy seed from that of Cain thy brother."
5 And God withdrew His Word from Seth.
6 Then Seth, Eve, and their children, came down from the mountain to the Cave of Treasures.
7 But Adam was the first whose soul died in the land of Eden, in the Cave of Treasures; for no one died before him, but his son Abel, who died murdered.
8 Then all the children of Adam rose up, and wept over their father Adam, and made offerings to him, one hundred and forty days.
