1413. 'To the land which I will cause you to see' means the spiritual and celestial things that were to be brought to view. This is clear from the meaning of 'a land', 662, 1066, and indeed from the meaning here of 'the land of Canaan' which represents the Lord's kingdom, as becomes clear from many places in the Word. For this reason the land of Canaan is called the Holy Land, and also the heavenly Canaan. And since it represented the Lord's kingdom, it also represented and meant the celestial and spiritual things that belong to the Lord's kingdom, and here those that belong to the Lord Himself.

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.
