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.

5817. 'And so it was, when we went up to your servant my father' means a raising up to spiritual good. This is clear from the meaning of 'going up' as a raising up, dealt with below; and from the representation of Israel, to whom 'father' refers here, as spiritual good from the natural, dealt with in 4286, 4598. A raising up of the kind meant here by 'going up is a movement towards more internal things; here it is a raising up from the truths in the natural, which are represented by 'Jacob's ten sons', to spiritual good from the natural, represented by 'Israel'. For there is an exterior natural and there is an interior natural, 5497, 5649. The interior natural holds spiritual good, which is 'Israel', while the exterior natural holds the truths known to the Church, which are 'Jacob's sons', and therefore 'going up to their father' means a raising up of these to spiritual good.
