Hand
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.
Arcana Coelestia # 4298
4298. 'And Jacob called the name of the place Peniel' means a state of temptations. This is clear from the train of thought, for in former times names were given to places where some special incident took place, and those names served to mean that incident which took place there, and the state associated with it, 340, 2643, 3422. To this place a name was given which meant a state of temptations, because it is a state of temptations that is described here by Jacob's wrestling and contending. In the original language 'Peniel' means 'the face of God', and the fact that 'seeing the face of God' means suffering the severest temptations will be explained in what follows immediately below.
