Enoch 6: “And Semjâzâ, who was their leader, said unto them: 'I fear ye will not indeed agree to do this deed, and I alone shall have to pay the penalty of a great sin.' 4. And they all answered
him and said: 'Let us all swear an oath, and all bind ourselves by mutual imprecations not to abandon this plan but to do this thing.' 5. Then sware they all together and bound themselves by mutual imprecations upon it. 6. And they were in all two hundred; who descended“
Mutually assured destruction oath of the fallen angels. And where they each went, they all went.
