Arcana Coelestia # 351
351. That 'Abel' means charity has been shown already. Charity means love towards the neighbour and compassion, for anyone who loves his neighbour as himself also has as much compassion for him in his suffering as he does for himself in his own.
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.
