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.

3171. 'And they rose up in the morning' means a degree of raising up. This is clear from the meaning of 'rising up' as implying a raising up, dealt with in 2401, 2785, 2912, 2927, and from the meaning of 'the morning' as the Lord, also His kingdom, as well as the state of peace which this brings, dealt with in 2405, 2780. The natural is said to be raised up when spiritual things are made over to it as its own. All raising up originates in spiritual and celestial things, for it is by means of these that a person is raised up to heaven and so nearer to the Lord.
