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.

7999. 'A purchase paid for with silver' means who is in possession of some spiritual truth. This is clear from the meaning of 'a purchase' as that which is acquired and made one's own, dealt with in 4397, 4487, 5374, 5397, 5406, 5410, 5426; and from the meaning of 'silver' as truth, dealt with in 1551, 2954, 5658, at this point spiritual truth since a slave who was bought means in the internal sense the natural man, and the master who bought him therefore means the spiritual man. No one can know what this really implies unless he knows in what way the spiritual buys the natural for itself, that is, acquires and makes it its own. When a person is being regenerated his internal and external, that is, his spiritual and natural, are at variance with each other at first; for his spiritual desires the things of heaven, whereas his natural desires those of the world. But at this time the spiritual is constantly entering the natural and bringing it into agreement. This is done by means of truth; and what the spiritual brings into agreement with itself within the natural is said to be 'bought with silver', that is, acquired and made its own by means of truth.
