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.

1941. 'And it will not be numbered for multitude' means being multiplied immeasurably. This is clear without explanation. By these words is meant the truth which in this manner will increase immeasurably from good. Because with the Lord, who is the subject here in the internal sense, all things are Divine and Infinite, these matters as they apply to Him cannot be put into words. Consequently, so that some idea may be obtained of what the multiplication of truth from good entails, it must be spoken of as it applies to man. In his case, if governed by good, that is, by love and charity, seed from the Lord is made fruitful and is multiplied to such an extent that it cannot be numbered for multitude. That fruitfulness and multiplication is not very much during his life in the body, but in the next life it is unbelievably increased, for as long as he lives in the body it is seed Lying in ground of a bodily nature, among an entangled and dense mass of factual knowledge and bodily delights, and also cares and anxieties. But once these have been cast off, as happens when he passes over into the next life, the seed is set free from those things and starts to grow, just like the seed of a tree which, when it comes up out of the ground, grows into a small tree, then into a large tree, and is after that multiplied into a garden of trees. For all knowledge, intelligence, and wisdom, and the forms of delight and happiness that go with them, are in a similar way made fruitful and are multiplied, and are thereby for ever increasing. And they begin from the smallest of seeds, as the Lord teaches in Matthew 13:31, by reference to the grain of mustard seed. This becomes quite clear from the knowledge, intelligence, and wisdom that angels possess, which during the time they were men had been to them beyond words.
