Arcana Coelestia #486
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.
Arcana Coelestia #7134
7134. 'As when there was straw' means as they had served their truths so called. This is clear from the meaning of 'straw' as the general kind of factual knowledge, which is a vessel for truth, dealt with in 7112, 7131. The reason why the expression 'truths so called' is used is that these are spoken by the evil, who do not consider truths to be truths.
