8877. 'On the third and on the fourth [generations]' means in a long sequence, and joined together. This is clear from the meaning of 'three' as what is complete from start to finish, dealt with in 2788, 4495, 7715, thus a long sequence, so that 'the third [generation on sons' is falsities in a long sequence (for the meaning of 'sons' as falsities, see immediately above in 8876); and from the meaning of 'four', like two, as joined together, dealt with in 1686, 5194, 8423, so that 'the third and the fourth [generations of] sons' are falsities joined together in a long sequence. This explanation of 'the third and the fourth [generations of] sons' must inevitably seem to be nonsensical or foreign to the meaning of the Word; but it should be remembered that in the internal sense numbers do not mean numbers but real things, see 482, 487, 575, 647, 648, 755, 813, 1963, 1988, 2075, 2252, 3252, 4264, 4495, 4670, 5265, 6175.

577. Twelve means faith, or those things in their entirety that belong to love and faith deriving from it. Many details from the Word may confirm this - the twelve sons of Jacob and their names, the twelve tribes of Israel, and the Lord's twelve disciples. These matters however will in the Lord's Divine mercy be dealt with later on, in particular in Genesis 29, 30.
