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.

3170. 'And they stayed the night' means its peace. This is clear from the meaning of 'staying the night' as resting, and in the internal sense as having peace. The implications of this are that when spiritual things become made over to the natural man, those things depart which are all part of evil desire and false persuasion, and so things which cause unrest; and those come in which are part of the affection for good and truth, and so the things that bring peace. For all unrest is the result of evil and falsity, and all peace the result of good and truth. What peace is, and the nature of its state, see 92, 93, 1726, 2780.
