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.

173. The things which come into existence in the heavens do not do so in the same manner as do the things on earth. In the heavens, all things come into existence from the Lord in accordance with their correspondences with the interiors of the angels. For angels have both interiors and exteriors. All things in their interiors have relation to love and faith, thus to the will and the understanding, for the will and the understanding are their receptacles, while their exteriors correspond to their interiors. That exteriors correspond to interiors may be seen above (87-115). This can be illustrated by what has been said above about the heat and light of heaven-that angels have heat in accordance with the quality of their love, and light in accordance with the quality of their wisdom (see 28-134). The same is true of all other things that present themselves before the senses of the angels.
