Hands in the Bible represent power, the force with which things are put into action. To be specific, they represent the power of spiritual good -- which is the love of others and serving others -- expressed through spiritual truth -- which is an understanding and knowledge of what it is to love and serve others. This is in contrast to the feet, which represent power on the natural level, and a “rod,” which represents the power of the hand passed down into external or natural ideas. In a few cases in the Bible, hands also represent communication and a drawing together. This is true when people lift their hands to heaven or to Jehovah, and also when the Lord touches children or touches people to heal them.

7011. 'And you are to take this rod in your hand' means Divine power in these [two kinds of truth]. This is clear from the meaning of 'rod' as power, dealt with in 4013, 4015, 4876, 4936, especially when it is held in the hand since 'hand' means spiritual power and 'rod' natural power.

There is no power at all in the natural unless it receives it from the spiritual, just as a rod has none unless it is held in the hand; and that is why it says that he was 'to take it in his hand'. Used in reference to the Lord 'hand' means the power going forth from His Divine Rational, and 'rod' the power going forth from His Divine Natural, see 6947. Divine power is said to be in these - the kinds of truth dealt with above - because power has reference to truth, 3091, 6344, 6427, 6948.
