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 #1732
1732. 'Blessed be Abram by God Most High' means that the Lord's Interior Man had the enjoyment of goods coming from His Internal Man. Similarly, this is clear from the meaning of 'blessing' as having the enjoyment of goods, as has been stated; also from the meaning of 'Abram' here as the Interior or Rational Man, dealt with above at verse 13; and then from the meaning of 'God Most High' as the Lord's Internal Man, also dealt with already. 'Abram', as has been stated, means the Interior or Rational Man, which was to be united to the Internal Man, or Jehovah, which union was accomplished through the conflicts that constituted temptations, and through victories. Indeed the situation with the Interior Man is that the Interior Man, as has been stated, is situated between the Internal Man and External Man, and enables the Internal Man to flow into the External. Without that Interior Man no communication takes place, and when it does take place it is a communication of celestial and spiritual things. When the communication was one of celestial things, the Interior Man was called 'Melchizedek', but when the communication was one of spiritual things it is called 'Abram the Hebrew'.
