This is clear from the meaning of 'man against son and against brother', or after they have killed them, as a shutting off of the internal to prevent the inflow of truth and good, dealt with above in 10490, 10492.

'Son' means truth, see 489, 491, 533, 1147, 2623, 2628, 2803, 2813, 3373, 3704, 4257, 9807.

'Brother' means good, 3815, 4121, 4191, 5409, 5686, 5692, 6756.

Both those Churches called Methuselah and Lamech breathed their last just before the flood.
