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.

4757. 'And they drew Joseph out and caused him to come up out of the pit' means the help provided by these so that [Divine Truth] is no longer among falsities. This is clear from the meaning of 'drawing out and causing to come up' as delivering and therefore as providing help, dealt with below, and from the meaning of 'the pit' as falsities, dealt with in 4728, and so as its being no longer among falsities. The reason 'drawing out and causing to come up' here means providing help is that truth is what brings help to good. For truth has power attributed to it because good exercises its power by means of truth, 3091, 3563. Furthermore truth is the means by which falsity is recognized, and so by which help is provided so that it is no longer among falsities. This is the reason why it was the Midianites who drew Joseph out and caused him to come up out of the pit, but why it was the Ishmaelites who bought him.
