486. Verse 4 And the days of Man after he beget Seth were eight hundred years; and he beget sons and daughters.

'Days' means periods of time and states in general. 'Years' means periods of time and states in particular. 'Sons and daughters' means the truths and goods that they perceived.

7649. 'Which your fathers and your fathers' fathers have not seen, from the day they have been on the ground even to this day' means that since ancient times no such falsity had existed in the Church as existed there now. This is clear from the meaning of 'which (that is, the locusts) they have not seen' as no such falsity had existed, 'locusts' being falsity in outermost parts, see above in 7643; from the meaning of 'fathers, and fathers of fathers' as since ancient times; and from the meaning of 'the ground' as the Church, dealt with in 566, 1068. 'From the day they have been on it even to this day' means the state in which the Church existed from that time to this, the state being meant by 'the day', see 23, 487, 488, 493, 2788, 3462, 4850. For more on this, see 7686.
