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.

9226. 'Seven days it shall be with its mother' means their first state with truths. This is clear from the meaning of 'seven days' as the first state of those who are being regenerated, 'days' being states, 23, 487, 488, 493, 893, 2788, 3462, 3785, 4850, 5672, 5962, 8426, 9213, and 'seven' being from start to finish, thus what is complete, 728, 6508; and from the meaning of 'mother' as the Church in respect of truth, thus also the Church's truth, dealt with in 289, 2691, 2717, 3703, 4257, 5581, 8897. From all this it follows that 'seven days it shall be with its mother' means the first state in its completeness or the whole of it from start to finish, during which a person is governed by truths. The implications of all this will be stated in the next paragraph.
