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.

4616. 'And the days of Isaac were' means the state of the Divine Rational at this point. This is clear from the meaning of 'days' as states, dealt with in 23, 487, 488, 493, 893, 2788, 3462, 3785, and from the representation of 'Isaac' as the Divine Rational, dealt with immediately above in 4615.
