Who are the "sons of God" who fathered the giants? The books disagree.

The books in this archive give four different answers. In the Book of Enoch they are angels, the Watchers: two hundred of them come down on Mount Hermon in the days of Jared, bind themselves by an oath and take human wives. Jubilees agrees that "the angels of God" took wives.

The Testament of Reuben keeps the Watchers but changes the story. The women allured them, and the Watchers took the shape of men and appeared to the women, who conceived giants through desire for these apparitions.

The Kebra Nagast says the angels had reviled Adam for his sin and asked to be tested. God gave them flesh, blood and a human heart, and they went down to the revels of the children of Cain and took wives there.

The Cave of Treasures rejects the angel account outright. Its "sons of God" are the children of Seth, who break their oaths, go down from the holy mountain to the daughters of Cain and cannot climb back. The writer calls the older version an error, because spirits have neither male nor female and cannot beget.
