{ The giants begin to be troubled by a series of dreams and visions Mahway, the titan son of the angel Barakel, reports the first of these dreams to his fellow giants. He sees a tablet being immersed in water. When it emerges, all but three names have been washed away. Teh dream evidently symbolizes the destruction of all but Noah, and his sons by the Flood.}
2Q26 [...]they drenched the tablet in the wa[ter...] [...] the waters went up over the [tablet...] [...] they lifted out the tablet from the water of [...]

{The giant goes to the others and they discuss the dream}
4Q530 Frag 7 [...this vision] is for cursing and sorrow. I am the one who confessed [...] the whole group of the castaways that I shall go to [...] [...the spirits of the sl]ain complaining about their killers and crying out [...] that we shall die together and be made an end of [...] much and I will be sleeping , and bread [...] for my dwelling; the vision and also [...] entered into the gathering of the giants [...]

{The giants realize the futility of fighting against the forces of Heaven. The first speaker may be Gilgamesh}

{More dreams afflict the giants. The details of this vision are obscure, but it bodes ill for the giants. The dreamers speak first to the monsters, then to the giants.}
Thereupon two of them had dreams and the sleep of their eyes fled from them, and they arose and came to [...and told] their dreams, and said in the assembly of [their comrades] the monsters [...In] my dream I was watching this very night [and there was a garden...] gardeners and they were watering [...two hundred trees and] large shoots came out of their root [...] all the water, and the fire burned all[the garden...] They found the giants to tell them [the dream...]

{Someone suggests that Enoch be found to interpret the vision}
[...to Enoch] the noted scribe, and he will interpret for us the dream. Thereupon his fellow Ohya declared and said to the giants, I too had a dream this ight, O giants, and, behold, the Ruler of Heaven came down to earth [...] and such is the end of the dream. [Thereupon] all the giants [and monsters] grew afraid and called Mahway. He came to them and the giants pleaded with him and sent him to Enoch [the noted scribe]. They said to him, Go [...] tho you that [...] you have heard his voice. And he said to him, He will [...and] interpret the dreams [zzz] Col 3 [...] how long the giants have to live. [....]

{After a cosmic journey, Mahway comes to Enoch and makes his request}

If [...] has been carried [...] from the days of [...] their[...] and they will be added [...] [...] we would know from you their meaning [...] [...two hundred tr]ees than from heaven [came down...]

{Enoch sends back a tablet with its grim message of judgement, but with hope for repentance.}
4Q530 Frag 2 The scribe [Enoch...] [...] a copy of the second tablet that [Enoch] se[nt...] in the very handwriting of Enoch the noted scribe [...In the name of God the great] and holy one, to Shemihaza and all [his companions] let it be known to you that not [...] and the things you have done, and that your wives [...] they and their sons and the wives of [their sons] by your licentiousness on the earth, and theer has been upon you [...and the land is crying out] and complaining about you and the deeds of your children [...] the harm that you have done to it [...] until Raphael arrives, behold, destruction [is coming, a great flood, and it will destroy all living things] and whatever is in the deserts and the seas.
