Arcana Coelestia#8714
8714. 'Rulers of fifties' means first and foremost truths that are intermediary. This is clear from the meaning of 'rulers' as first and foremost truths, as above in 8712, 8713; and from the meaning of 'fifties' as intermediary truths, that is to say, those which lie between truths springing from good that reside in the second degree and those that reside in the third, meant by 'rulers of hundreds' and 'rulers of tens'. The reason why 'fifties' are intermediary truths is that 'fifty' means either much or something, just as 'five' does (for the meaning of 'five' as much, see 5708, 5956, and for its meaning something, 4638, 5291), and therefore when fifty is mentioned between a hundred and ten, intermediaries are meant. Intermediary truths are those which extend towards one part from another, that is, exist between those in a prior degree and those in a posterior degree, in order to link such degrees together.

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.
