"... More veiled allusions to punishment through the deluge may be reflected by the language of Sirach 16:7 (‘[God] did not forgive the giants of old’) and the Damascus Document (‘... and their sons whose height was as the height of cedars and whose bodies were as mountains [were caught] because they fell. All flesh which was on dry land decayed and became as if they never were.’). Other traditions allowed—similar to the Book of Watchers, Book of Giants, Jubilees - for the giants to persist beyond death, perhaps alongside the fallen angels, in a disembodied form of existence as spirits. This is presupposed in the sapiential songs document in 4Q510 and 4Q511, where the ‘spirits of the bastards’ are reckoned as powers with which the righteous still have to contend. In the later Christian Testament of Solomon (5:3; 17:1), the link between the post-diluvian demons and the giant offspring of the fallen angels is made explicit. This raises the possibility that would require more analysis than is possible here, namely, that mythological traditions about the giants may already have been adapted in passages of the gospels in which the desire of spirits to enter into human bodies is presupposed (so e.g. Mark 5:1–20; Matthew 12:43–45 / Luke 11:24–26) ..."
