860. From these considerations it also becomes clear that all regeneration advances from evening to morning, as is mentioned six times in Genesis 1 where the regeneration of man is the subject.

4780. 'And mourned over his son many days' means a state, namely one of mourning for lost good and truth. This is clear from the representation of Joseph, to whom 'son' refers here, as Divine Truth, specifically the truths spoken of above in 4776; and from the meaning of 'days' as states, dealt with in 23, 487, 488, 493, 893, 2788, 3785, in this case a state of great mourning since the expression 'many days' is used.
