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.

258. 'Treading down' or bruising is used to mean forcing down so that it goes on its belly and eats dust. This is clear from this and from the previous verse. A similar usage also occurs in Isaiah, Jehovah has cast down the inhabitants of the height, the lofty city. He will lay it low, He will lay it low even to the ground, He will throw it down even into the dust. The foot will trample on it. Isaiah 16:5, 6.

And also,

With His hand He will cast them down to the earth, they will be trodden under foot, the haughty crown. Isaiah 28:2-3.
