9488. 'And a cubit and a half its breadth' means what is complete so far as truth is concerned. This is clear from the meaning of 'one and a half' as what is complete, the reason why this number means what is complete being that 'three' has this meaning (for the half of a number is similar in meaning to the whole number, because a number that results from multiplication keeps the same meaning as a simple number of which it is the product through multiplication, 5291, 5335. Regarding 'three', that it means what is complete, see 2788, 7715, 9198; and that all numbers in the Word mean spiritual realities, 482, 487, 575, 647, 648, 755, 813, 1963, 1988, 2075, 2252, 3252, 4264, 4495, 4670, 5265, 5291, 5335, 5708, 6175, 7973); and from the meaning of 'breadth' as truth, dealt with immediately above in 9487.
Arcana Coelestia #9326
9326. 'I will fulfill the number of your days' means all the way to a state of completeness. This is clear from the meaning of 'days' as states of life, dealt with in 23, 487, 488, 493, 893, 2788, 3462, 3785, 4850, 5672, 5962, 6110, 7680, 8426, in this instance the state of new life or spiritual life, which is that of one who has been regenerated; and from the meaning of 'fulfilling the number' as continuing to completeness. All the way to a state of completeness means even until a person has been regenerated. The development of the truths and forms of good in their proper order, in continuous progression - meant by the words 'none will suffer miscarriage or be barren in the land', dealt with immediately above in 9325 - continues all the way to such completeness.
Arcana Coelestia #3252
3252. 'A hundred and seventy-five years' means the things constituting that state. This becomes clear from the fact that every number used in the Word means some real thing, see 482, 487, 575, 647, 648, 1963, 1988, 2075, 2252, and so with this particular number which consequently means the things which constitute the state that is the subject here. As long as the mind confines itself to the historical sense it seems as though numbers, such as these 1 which give Abraham's age, do not hold any interior meaning within them. The fact that they do nevertheless hold such meaning within them is evident from all that has been shown already concerning numbers, and becomes clear from the consideration that no number as to its numerical value contains anything holy, and yet the smallest detail of all in the Word is holy.
