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.

8216. 'And made them drive heavily' means resistance and lack of power. This is clear from the meaning of 'wheels' as the power to advance falsities, dealt with immediately above in 8215, so that 'making them drive heavily' means being hindered by resistance, and therefore means lack of power.
