The idea of "lifting" is used in a number of different ways in the Bible. In general, it means connecting with a higher spiritual state for strength or enlightenment, though as with many verbs the context makes a great deal of difference. One of the most common uses comes as people lift up their eyes, which usually means coming into a state of perceiving what is true from the Lord. Lifting a hand or a rod means wielding power, making it common in the performance of miracles. Lifting the feet means elevating the most natural, external aspects of our day-to-day lives. Lifting objects means elevating them to higher uses, or sometimes just to protect them (Noah's Ark was "lifted up" in this sense). And so forth. In the negative sense, people can lift things up -- towers or other human structures -- representing a deeper state of the love of self.

6947. 'What is that in your hand? And he said, A rod' means the power of the Lord's Divine Human. This is clear from the meaning of 'hand' as power, dealt with in 878, 3387, 4931-4937, 5327, 5328, 5544; and from the meaning of 'a rod' too as power, dealt with in 4013, 4876, 4936. The reason why it is the power of the Lord's Divine Human is that 'Moses' represents the Lord in respect of the law of God, which is the Word, and this is Divine Truth emanating from the Lord's Divine Human, 6752. The power meant by 'hand' is the power emanating from the Lord's Divine Rational, whereas the power meant by 'the rod' is the power emanating from the Lord's Divine Natural. The reason why 'a rod' is the power emanating from the Lord's Divine Natural is that a rod is like a foot in that it supports the body, and by 'the foot' is meant the natural, 2161, 3147, 3761, 3986, 4280, 4938-4952; and 'lifting up the hand' is power in the spiritual, while 'lifting up the foot' is power in the natural, see 5727, 5328. And since 'hand' and 'rod' have these meanings, then depending on how high the things described in the internal sense rise Moses was sometimes told, when he was to work miracles, to lift up his hand, at other times his rod.
