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.

6679. 'And did not do as the king of Egypt spoke to them' means that the intention of those under the influence of falsities was not carried out. This is clear from the meaning of 'did not do as he spoke' as the fact that their intention was not carried out, that is, they were unable to destroy the truths meant by 'the boys', even though their intention was to destroy them by whatever method they could, 6676; and from the meaning of 'the king of Egypt' as separated factual knowledge that is opposed to the Church's truth, dealt with in 6651, thus falsity since that factual knowledge is false.
