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 # 9423
9423. 'Until we return [to you]' means till there is a reply. This is clear from the meaning of 'returning' as a reply; for when 'sitting in this [place]' means remaining in that state, 9422, 'returning' means they are to be told what is to be done then, and so means a reply.
