Jude 1:9 yet Michael, the chief messenger, when, with the devil contending, he was disputing about the body of Moses, did not dare to bring up an evil-speaking judgment, but said, `The Lord rebuke thee!' 10 and these, as many things indeed as they have not known, they speak evil of; and as many things as naturally (as the irrational beasts) they understand, in these they are corrupted; 11 wo to them! because in the way of Cain they did go on, and to the deceit of Balaam for reward they did rush, and in the gainsaying of Korah they did perish.
DEVIL does not equate to a wicked rebel spirit/fallen angel, devil/diabolos means prone to slander, false accuser.
Men are indeed a devil/slanderers, and in the above passage the devil is said to be "these" "they" "them" who speak evil like irrational beasts who went in the way of Cain, went to deceit of Balaam for reward, and in the rebellion of Korah they did perish.
Numbers 14:35 I the LORD have said, I will surely do it unto all this evil congregation, that are gathered together against me: in this wilderness they shall be consumed, and there they shall die. 36 And the men, which Moses sent to search the land, who returned, and made all the congregation to murmur against him, by bringing up a slander upon the land, 37 Even those men that did bring up the evil report upon the land, died by the plague before the LORD.
Numbers 16:1 Now Korah, the son of Izhar, the son of Kohath, the son of Levi, and Dathan and Abiram, the sons of Eliab, and On, the son of Peleth, sons of Reuben, took men: 2 And they rose up before Moses, with certain of the children of Israel, two hundred and fifty princes of the assembly, famous in the congregation, men of renown: 3 And they gathered themselves together against Moses and against Aaron, and said unto them, Ye take too much upon you, seeing all the congregation are holy, every one of them, and the LORD is among them: wherefore then lift ye up yourselves above the congregation of the LORD? 4 And when Moses heard it, he fell upon his face: 5 And he spake unto Korah and unto all his company, saying, Even to morrow the LORD will shew who are his, and who is holy; and will cause him to come near unto him: even him whom he hath chosen will he cause to come near unto him. 6 This do; Take you censers, Korah, and all his company; 7 And put fire therein, and put incense in them before the LORD to morrow: and it shall be that the man whom the LORD doth choose, he shall be holy: ye take too much upon you, ye sons of Levi. 8 And Moses said unto Korah, Hear, I pray you, ye sons of Levi: 9 Seemeth it but a small thing unto you, that the God of Israel hath separated you from the congregation of Israel, to bring you near to himself to do the service of the tabernacle of the LORD, and to stand before the congregation to minister unto them? 10 And he hath brought thee near to him, and all thy brethren the sons of Levi with thee: and seek ye the priesthood also? 11 For which cause both thou and all thy company are gathered together against the LORD: and what is Aaron, that ye murmur against him? 12 And Moses sent to call Dathan and Abiram, the sons of Eliab: which said, We will not come up: 13 Is it a small thing that thou hast brought us up out of a land that floweth with milk and honey, to kill us in the wilderness, except thou make thyself altogether a prince over us? 14 Moreover thou hast not brought us into a land that floweth with milk and honey, or given us inheritance of fields and vineyards: wilt thou put out the eyes of these men? we will not come up. 15 And Moses was very wroth, and said unto the LORD, Respect not thou their offering: I have not taken one ass from them, neither have I hurt one of them. 16 And Moses said unto Korah, Be thou and all thy company before the LORD, thou, and they, and Aaron, to morrow: 17 And take every man his censer, and put incense in them, and bring ye before the LORD every man his censer, two hundred and fifty censers; thou also, and Aaron, each of you his censer. 18 And they took every man his censer, and put fire in them, and laid incense thereon, and stood in the door of the tabernacle of the congregation with Moses and Aaron. 19 And Korah gathered all the congregation against them unto the door of the tabernacle of the congregation: and the glory of the LORD appeared unto all the congregation. 20 And the LORD spake unto Moses and unto Aaron, saying, 21 Separate yourselves from among this congregation, that I may consume them in a moment. 22 And they fell upon their faces, and said, O God, the God of the spirits of all flesh, shall one man sin, and wilt thou be wroth with all the congregation? 23 And the LORD spake unto Moses, saying, 24 Speak unto the congregation, saying, Get you up from about the tabernacle of Korah, Dathan, and Abiram. 25 And Moses rose up and went unto Dathan and Abiram; and the elders of Israel followed him. 26 And he spake unto the congregation, saying, Depart, I pray you, from the tents of these wicked men, and touch nothing of theirs, lest ye be consumed in all their sins. 27 So they gat up from the tabernacle of Korah, Dathan, and Abiram, on every side: and Dathan and Abiram came out, and stood in the door of their tents, and their wives, and their sons, and their little children. 28 And Moses said, Hereby ye shall know that the LORD hath sent me to do all these works; for I have not done them of mine own mind. 29 If these men die the common death of all men, or if they be visited after the visitation of all men; then the LORD hath not sent me. 30 But if the LORD make a new thing, and the earth open her mouth, and swallow them up, with all that appertain unto them, and they go down quick into the pit; then ye shall understand that these men have provoked the LORD. 31 And it came to pass, as he had made an end of speaking all these words, that the ground clave asunder that was under them: 32 And the earth opened her mouth, and swallowed them up, and their houses, and all the men that appertained unto Korah, and all their goods. 33 They, and all that appertained to them, went down alive into the pit, and the earth closed upon them: and they perished from among the congregation.
Numbers 31:11 And they took all the spoil, and all the prey, both of men and of beasts. 12 And they brought the captives, and the prey, and the spoil, unto Moses, and Eleazar the priest, and unto the congregation of the children of Israel, unto the camp at the plains of Moab, which are by Jordan near Jericho.13 And Moses, and Eleazar the priest, and all the princes of the congregation, went forth to meet them without the camp. 14 And Moses was wroth with the officers of the host, with the captains over thousands, and captains over hundreds, which came from the battle. 15 And Moses said unto them, Have ye saved all the women alive? 16 Behold, these caused the children of Israel, through the counsel of Balaam, to commit trespass against the LORD in the matter of Peor, and there was a plague among the congregation of the LORD.
There is no reference in JUDE 1 to wicked rebel spirits/fallen angels. JUDE 1 is about certain MEN, we are given examples of men from the OT, men who are natural men, like ignorant beasts who have not the Spirit of God and go about being murmurers/slanderers, walking according to their desires for profit.
Jude 1:12 These are in your love-feasts craggy rocks; feasting together with you, without fear shepherding themselves; clouds without water, by winds carried about; trees autumnal, without fruit, twice dead, rooted up; 13 wild waves of a sea, foaming out their own shames; stars going astray, to whom the gloom of the darkness to the age hath been kept. 14 And prophesy also to these did the seventh from Adam -- Enoch -- saying, `Lo, the Lord did come in His saintly myriads, 15 to do judgment against all, and to convict all their impious ones, concerning all their works of impiety that they did impiously, and concerning all the stiff things that speak against Him did impious sinners.' 16 These are murmurers, repiners; according to their desires walking, and their mouth doth speak great swellings, giving admiration to persons for the sake of profit; 17 and ye, beloved, remember ye the sayings spoken before by the apostles of our Lord Jesus Christ: 18 that they said to you, that in the last time there shall be scoffers, after their own desires of impieties going on, 19 these are those setting themselves apart, natural men, the Spirit not having. 20 And ye, beloved, on your most holy faith building yourselves up, in the Holy Spirit praying,
