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 # 7872
7872. 'From man even to beast' means their evil desires, interior and exterior. This is clear from the meaning of 'from man even to beast' as the affection for interior good and exterior good, dealt with in 7424, 7523; for 'man' means the affection for interior good, and 'beast' the affection for exterior good. In the contrary sense, as at this point where the firstborn of the Egyptians are referred to, evil affections, or interior and exterior evil desires, are meant. For more about the meaning of 'beasts' as good affections, and in the contrary sense evil affections or desires, see 45, 46, 142, 143, 246, 714, 715, 719, 776, 1823, 2179, 2180, 2781, 3218, 3519, 5198.
