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.

7569. 'And there will be hail in all the land of Egypt' means destructive falsity in the natural mind. This is clear from the meaning of 'hail' as destructive falsity arising from evils - destructive of all the goodness and truth of the Church, dealt with in 7553; and from the meaning of 'the land of Egypt' as the natural mind, dealt with in 5276, 5278, 5280, 5288, 5301.
