Enoch 10:15, 16

To Michael also, the Lord said, Go and announce his crime to Samyaza and to the others who are with him who have been associated with women... Bind them for seventy generations underneath the earth, even to the day of judgment, and of consumation , until the judgment, which shall last forever, be completed. Then shall they be taken away into the lowest depths of the fire in torments, and in confinement shall they be shut up forever.

Jude 6 2 Peter 2:4 Revelation 20:10

The angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness, unto the judgment of the great day. God spared not the angels when they sinned, but cast them down to hell, and committed them to pits of darkness, to be reserved unto judgment. The devil that deceived them was cast into the lake of fire and brimstone... and shall be tormented day and night forever.

the Lord said to Raphael: 'Bind Azâzêl hand and foot, and cast him into the darkness: and make an opening in the desert, which is in Dûdâêl, and cast him therein.
Enoch 10:4

bind Semjâzâ and his associates ... bind them fast for seventy generations in the valleys of the earth
Enoch 10:11

‘Dudael’ refers, ‘Dudael’ also means ‘Great Desert’ and ‘Fiery Caldron.’ Furthermore, there is one place in Israel that fits that description: the Negev, which has one of its borders on…Gaza/Aza.
Shemhazai was the leader of the fallen angels and Azazel taught humans how to make war and weapons.

⁹The spirits of the giants shall be like clouds, ⁽²⁵⁾ which shall oppress, corrupt, fall, content, and bruise upon earth.

(25) The Greek word for "clouds" here, nephelas, may disguise a more ancient reading, Napheleim (Nephilim).

¹⁰They shall cause lamentation. No food shall they eat; and they shall be thirsty; they shall be concealed, and shall not ⁽²⁶⁾ rise up against the sons of men, and against women; for they come forth during the days of slaughter and destruction.

(26) Shall not. Nearly all manuscripts contain this negative, but Charles, Knibb, and others believe the "not" should be deleted so the phrase reads "shall rise up."

Repeat ref.
15:9 The spirits of the giants shall be like clouds, which shall oppress, corrupt, fall, contend, and bruise upon Earth.

15:10 They shall cause lamentation. No food shall they eat; and they shall be thirsty; they shall be concealed, and those spirits (demons) shall rise up against the sons of men, and against women; for they come forth during the days of slaughter and destruction (Luke 4:33, 36; Matt. 8:28‑34).
