It is common in the Bible for people to "rise up," and it would be easy to pass over the phrase as simply describing a physical action. But in fact it represents an elevation in spiritual state, moving to a more internal frame of mind closer to the Lord. Often it has to do with understanding a new or important idea; we "rise up" to a state of greater perception and enlightenment. Obviously context is crucial to the exact meaning of the phrase in a given passage -- it matters greatly who it is that is rising up, and why.

272. There is a still further reason, and this is in heaven the primary reason, why the angels are able to receive so great wisdom, namely, that they are without the love of self; for to the extent that any one is without the love of self he can become wise in Divine things. It is that love that closes up the interiors against the Lord and heaven, and opens the exteriors and turns them toward itself; and in consequence all in whom that love rules are in thick darkness in respect to the things of heaven, however much light they may have in worldly matters. The angels, on the other hand, are in the light of wisdom because they are without the love of self, for the heavenly loves in which they are, which are love to the Lord and love towards the neighbor, open the interiors, because these loves are from the Lord and the Lord Himself is in them. (That these loves constitute heaven in general, and form heaven in each one in particular, may be seen above, 13-19). As heavenly loves open the interiors to the Lord so all angels turn their faces towards the Lord (142); because in the spiritual world the love turns the interiors of everyone to itself, and whichever way it turns the interiors it also turns the face, since the face there makes one with the interiors, for it is their outward form. Because the love turns the interiors and the face to itself, it also conjoins itself to them (love being spiritual conjunction), and shares its own with them. From that turning and consequent conjunction and sharing the angels have their wisdom. That all conjunction and all turning in the spiritual world are in accord may be seen above (255).
