Apocalypse Revealed #415
415. And I looked, and I heard an angel flying in the midst of heaven. (8:13) This symbolizes instruction and prediction from the Lord.
In the highest sense an angel means the Lord, and so also something from the Lord (no. 344). And to fly in the midst of heaven and speak means, symbolically, to perceive and understand, and when said of the Lord, to foresee and provide (no. 245). But here it means to instruct and predict.
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.
