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.

10454. 'And Joshua heard the noise of the people as they shouted' means contemplating and discerning what the interiors of that nation were like. This is clear from the meaning of 'hearing' as contemplating and discerning, for the subject now is what that nation was like inwardly, thus what their interiors were like; from the representation of 'Joshua' as the truth of the Word contemplating and discerning (he was Moses' minister, and Moses represented the Word, as shown above, so that his minister represents truth, for all truth belongs to the Word, at this point truth that contemplates, examines, and discerns); and from the meaning of 'the noise of the people as they shouted' as what that nation was like inwardly, thus what their interiors were like. In the Word 'noise' or 'voice' means the inner voice, which is thought, consequently what the interiors are like as regards either truth or falsity, for the one or the other gives rise to the thought, see 219, 220, 3563, 7573, 8813, 9926. But 'shouting' means the utterance of sound, whether that of speaking, singing, or crying out, which emanates from thought or the inner voice. So it is that 'hearing the noise of shouting' means discerning what the interiors are like from the sound that indicates it. For the sound, whether that of speaking, singing, or crying out, emanates from inner affection and thought, both of which are present within the sound and are also discerned by those who listen to it and think about it, to see for example whether it is angry, threatening, friendly, gentle, joyful, gloomy, and so on. In the next life such discernment is so sharp that angels can discern what someone's interiors are like from the sound of just one of the words he uses. This then is what 'hearing the noise of the people as they shouted' is used to mean.
