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.

7248. I have been told that the inhabitants of that planet who, when they die and become spirits, appear on this side of it derive the greatest pleasure out of acts of plunder, and most especially out of eating from the plunder. The delight they experience when they think about eating from the plunder was conveyed to me, and I perceived that it was very great. The fact that people with that kind of bestial nature have also inhabited our own planet is evident from the history of various nations, and also from the inhabitants of the land of Canaan, 1 Samuel 30:16, as well as from the Jewish and Israelite nation in David's time, in that they made raids every year on nations, pillaged them, and rejoiced in the pillage. So far as these inhabitants of the planet Venus are concerned, they do indeed find pleasure in acts of plunder; yet they are not cruel. They throw people whom they despoil into water, using that as the method to put them to death; but they keep alive those they can. They afterwards bury those whom they have put to death in that way, which shows that there is some humanity in them, unlike the Jews, whose delight it was to cast aside those they killed and expose them to be devoured by wild animals of the forest or by birds, and sometimes to put them to death in a savage and cruel manner, 2 Samuel 12:31. How much delight the Jews took in such practices I was also allowed to recognize in the sphere conveyed to me from those who, in great numbers, quickly came near and then fled.
