Jude 1:10-11
[10]Yet these people slander whatever they do not understand, and the very things they do understand by instinct—as irrational animals do—will destroy them.
[11]Woe to them! They have taken the way of Cain; they have rushed for profit into Balaam’s error; they have been destroyed in Korah’s rebellion.
The false teachers slandered what they did not understand. Jude compared them to animals that would destroy themselves by things they instinctively pursed.
Jude also compared the heretics to
Cain
Genesis 4:4-5,8-9
[4]And Abel also brought an offering—fat portions from some of the firstborn of his flock. The Lord looked with favour on Abel and his offering,
[5]but on Cain and his offering he did not look with favour. So Cain was very angry, and his face was downcast.
[8]Now Cain said to his brother Abel, “Let’s go out to the field.” While they were in the field, Cain attacked his brother Abel and killed him.
[9]Then the Lord said to Cain, “Where is your brother Abel?” “I don’t know,” he replied. “Am I my brother’s keeper?”
1 John 3:12
[12]Do not be like Cain, who belonged to the evil one and murdered his brother. And why did he murder him? Because his own actions were evil and his brother’s were righteous.
1 John 2:9-11
[9]Anyone who claims to be in the light but hates a brother or sister is still in the darkness.
[10]Anyone who loves their brother and sister lives in the light, and there is nothing in them to make them stumble.
[11]But anyone who hates a brother or sister is in the darkness and walks around in the darkness. They do not know where they are going, because the darkness has blinded them.
1 John 3:15
[15]Anyone who hates a brother or sister is a murderer, and you know that no murderer has eternal life residing in him.
1 John 4:19-20
[19]We love because he first loved us.
[20]Whoever claims to love God yet hates a brother or sister is a liar. For whoever does not love their brother and sister, whom they have seen, cannot love God, whom they have not seen.
Balaam
Numbers 31:16
[16]“They were the ones who followed Balaam’s advice and enticed the Israelites to be unfaithful to the Lord in the Peor incident, so that a plague struck the Lord’s people.
2 Peter 2:15
[15]They have left the straight way and wandered off to follow the way of Balaam son of Bezer, who loved the wages of wickedness.
And Korah
Numbers 16:1-35
[1]Korah son of Izhar, the son of Kohath, the son of Levi, and certain Reubenites—Dathan and Abiram, sons of Eliab, and On son of Peleth—became insolent
[2]and rose up against Moses. With them were 250 Israelite men, well-known community leaders who had been appointed members of the council.
[3]They came as a group to oppose Moses and Aaron and said to them, “You have gone too far! The whole community is holy, every one of them, and the Lord is with them. Why then do you set yourselves above the Lord’s assembly?”
[4]When Moses heard this, he fell facedown.
[5]Then he said to Korah and all his followers: “In the morning the Lord will show who belongs to him and who is holy, and he will have that person come near him. The man he chooses he will cause to come near him.
[6]You, Korah, and all your followers are to do this: Take censers
[7]and tomorrow put burning coals and incense in them before the Lord. The man the Lord chooses will be the one who is holy. You Levites have gone too far!”
[8]Moses also said to Korah, “Now listen, you Levites!
[9]Isn’t it enough for you that the God of Israel has separated you from the rest of the Israelite community and brought you near himself to do the work at the Lord’s tabernacle and to stand before the community and minister to them?
[10]He has brought you and all your fellow Levites near himself, but now you are trying to get the priesthood too.
[11]It is against the Lord that you and all your followers have banded together. Who is Aaron that you should grumble against him?”
[12]Then Moses summoned Dathan and Abiram, the sons of Eliab. But they said, “We will not come!
[13]Isn’t it enough that you have brought us up out of a land flowing with milk and honey to kill us in the wilderness? And now you also want to lord it over us!
[14]Moreover, you haven’t brought us into a land flowing with milk and honey or given us an inheritance of fields and vineyards. Do you want to treat these men like slaves ? No, we will not come!”
[15]Then Moses became very angry and said to the Lord, “Do not accept their offering. I have not taken so much as a donkey from them, nor have I wronged any of them.”
[16]Moses said to Korah, “You and all your followers are to appear before the Lord tomorrow—you and they and Aaron.
[17]Each man is to take his censer and put incense in it—250 censers in all—and present it before the Lord. You and Aaron are to present your censers also.”
[18]So each of them took his censer, put burning coals and incense in it, and stood with Moses and Aaron at the entrance to the tent of meeting.
[19]When Korah had gathered all his followers in opposition to them at the entrance to the tent of meeting, the glory of the Lord appeared to the entire assembly.
[20]The Lord said to Moses and Aaron,
[21]“Separate yourselves from this assembly so I can put an end to them at once.”
[22]But Moses and Aaron fell facedown and cried out, “O God, the God who gives breath to all living things, will you be angry with the entire assembly when only one man sins?”
[23]Then the Lord said to Moses,
[24]“Say to the assembly, ‘Move away from the tents of Korah, Dathan and Abiram.’ ”
[25]Moses got up and went to Dathan and Abiram, and the elders of Israel followed him.
[26]He warned the assembly, “Move back from the tents of these wicked men! Do not touch anything belonging to them, or you will be swept away because of all their sins.”
[27]So they moved away from the tents of Korah, Dathan and Abiram. Dathan and Abiram had come out and were standing with their wives, children and little ones at the entrances to their tents.
[28]Then Moses said, “This is how you will know that the Lord has sent me to do all these things and that it was not my idea:
[29]If these men die a natural death and suffer the fate of all mankind, then the Lord has not sent me.
[30]But if the Lord brings about something totally new, and the earth opens its mouth and swallows them, with everything that belongs to them, and they go down alive into the realm of the dead, then you will know that these men have treated the Lord with contempt.”
[31]As soon as he finished saying all this, the ground under them split apart
[32]and the earth opened its mouth and swallowed them and their households, and all those associated with Korah, together with their possessions.
[33]They went down alive into the realm of the dead, with everything they owned; the earth closed over them, and they perished and were gone from the community.
[34]At their cries, all the Israelites around them fled, shouting, “The earth is going to swallow us too!”
[35]And fire came out from the Lord and consumed the 250 men who were offering the incense.
These men deceived others and are know for their hatred, greed( wages of wickedness) and rebellion to constituted authority.
