3016. 'Abraham, being old, was advanced in years' means when the state was reached in which the Lord's Human could become Divine. This is clear from the representation of 'Abraham' as the Lord, dealt with in 1893, 1965, 1989, 2011, 2172, 2198, 2501, 2833, 2836, and many times elsewhere; from the meaning of 'old' or old age as casting off what is human and putting on what is heavenly, dealt with in 1854, 2198, and when it has reference to the Lord, putting on what is Divine; and from the meaning of 'day' as state, dealt with in 23, 487, 488, 493, 893, 2788, and therefore from the meaning of 'advanced in years' as the point when a state has been reached. The reason why 'old' and 'advanced in years' mean these things is that with angels the notion of old age does not exist, nor that of getting older, meant by 'advanced in years', only the notion of state as regards the life that is theirs. Consequently when getting older or old age is mentioned in the Word the angels present with man can have no other idea than that of the state of life that is theirs or that is men's as they pass through the different stages of life until they reach the last, that is to say, as they accordingly cast off what is human and put on what is heavenly. For man's life from infancy to old age is nothing else than an advance from the world towards heaven, the last stage of which is death and the actual transition from one life to the next. Burial therefore is also resurrection since the casting-off process is completed then, 2916, 2917. Such being the idea that angels have, nothing else can be meant by 'advanced in years' and by 'old age' in the internal sense - the sense which exists primarily for angels and for men who have minds like those of angels.

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.
