8421. 'And it shall be on the sixth day' means at the end of each state. This is clear from the meaning of 'day' is state, dealt with in 23, 487, 488, 493, 2788, 3462, 3785, 4850, 7680; and from the meaning of 'the sixth' as the end of a state. The reason why 'the sixth day' means the end of a state is that 'seven days' or 'a week' means a whole period or complete state, 2044, 3845, 6508, and therefore the day before the seventh, which is 'the sixth', means the end of that state, while the day after, which is 'the eighth', means the beginning of the same state, 2044, 8400.

493. There is no need to pause too long over the consideration that 'days' and 'years mean periods of time and states. Only this need be stated here, that in the world periods of time and measurements to which numbers may be applied are indispensable, for they belong within the ultimate realms of nature. But whenever such application occurs, the numbers of days and years, and also the numbers applied to measurements, mean something which is completely different from periods of time or from measurements, and which is determined by the meaning of the number used, as in the statements about there being six days for work, and the seventh being holy, which are dealt with above; in the statement about a jubilee having to be announced every forty-ninth year and celebrated in the fiftieth; about the tribes of Israel being twelve, the same number as the Lord's Apostles; and about there being seventy elders, the same number as the Lord's disciples. And there are many other examples where the numbers mean some special characteristic completely different from the persons or objects to which they apply. And when completely separated one from the other the states meant by the numbers are then left.
