1 Enoch 10:13
11 And the Lord said unto Michael: 'Go, bind Semjâzâ and his associates who have united themselves with women so as to have defiled themselves with them in all their uncleanness. 12 And when their sons have slain one another, and they have seen the destruction of their beloved ones, bind them fast for seventy generations in the valleys of the earth, till the day of their judgement and of their consummation, till the judgement that is for ever and ever is consummated. 13 In those days they shall be led off to the abyss of fire: 〈and〉 to the torment and the prison in which they shall be confined for ever. And whosoever shall be condemned and destroyed will from thenceforth be bound together with them to the end of all generations.
Luke 8:31
29 For Jesus had started commanding the evil spirit to come out of the man. (For it had seized him many times, so he would be bound with chains and shackles and kept under guard. But he would break the restraints and be driven by the demon into deserted places.) 30 Jesus then asked him, “What is your name?” He said, “Legion,” because many demons had entered him. 31 And they began to beg him not to order them to depart into the abyss. 32 Now a large herd of pigs was feeding there on the hillside, and the demonic spirits begged Jesus to let them go into them. He gave them permission. 33 So the demons came out of the man and went into the pigs, and the herd of pigs rushed down the steep slope into the lake and drowned.
Notes and References
"... In 1 Enoch 10:12–13, the abyss (abussos) is the place where the offending Watchers (= sons of God of Genesis 6:1–4) are imprisoned “for seventy generations.” The partially synonymous relationship between the Abyss and the realm of the dead is indicated by the fact that some members of the abyss are imprisoned, unable to leave (the Watchers) whereas others (Satan, demons) are not so imprisoned. This may be what is behind the fear of the demons in Luke 8:31 (“And they begged him not to command them to depart into the abyss”; compare Matthew 8:29). Enoch visits the Abyss in 1 Enoch 21:7–10 ..."
