Arcana Coelestia # 342
342. That the second born of the Church is charity becomes clear from the things which the Church conceives and gives birth to, which are nothing other than faith and charity. The first of those born to Leah by Jacob had a similar meaning. Reuben meant faith; Simeon, faith expressed in action; Levi, charity, Genesis 29:32-34. This also was why the tribe of Levi assumed the function of the priesthood and became representative of the shepherd of the flock. Being the second born of the Church, charity is referred to as 'a brother. and is called 'Abel'.
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.
