Scientists believe that one of the most crucial developments in the evolution of humans was bipedalism – walking on two legs. That left our hands free to carry things, use tools, fight, work and touch each other. Having hands made intelligence important, leading to larger brains and, at some point, true humanity through spiritual existence.
We’ve been using our hands the same way ever since; they are the primary way we can put our thoughts and intentions into action. That was true in centuries past, as farmers, warriors, craftsmen and artists were all dependent on their hands. And while it might be slightly less true thanks to technology today, we still use primarily our hands to interface with machines through instruments and keyboards.
It makes sense, then, that 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.
457. Still did not repent of the works of their hands. This symbolically means, nor did they refrain from their native proclivities, which are evils of every kind, as being sins.
The works of a person's hands symbolize a person's native proclivities, which are evils and their attendant falsities, because the hands symbolize in summary the things that emanate from a person; for the forces of the mind and consequently of the body are directed into the hands and terminate there. Consequently the hands in the Word symbolize power. For the same reason the works of a person's hands symbolize his native proclivities, which are evils and falsities of every kind. Evils are the native proclivities of his will, and the attendant falsities the native proclivities of his intellect.
We are told regarding the people who are the subject here that they did not repent, because people who make faith alone the totality of religion say to themselves, "What need do I have of repentance, when through faith alone our sins are forgiven and we are saved? What do our works contribute to this? I know that I was born in sin and that I am a sinner. If I confess this and pray that my faults not be imputed to me, then I have repented. What need do I have of anything more?"
Thus the person then gives no thought to sin, even to the point of not knowing what sins are. Consequently the delight and gratification they afford continually carry him along in them and into them, the way a favorable wind and current carry a ship onto rocks when both captain and crew are asleep.

 In the natural sense of the Word, the works of a person's hands mean carved images, cast images, and idols; but in its spiritual sense, they symbolize evils and falsities of every kind, which are a person's native proclivities. As, for example, in the following passages:
...do not provoke Me to anger by the work of your hands...; (if you were) to provoke Me to anger by the work of your hands to your own hurt..., I will repay them according to their work and according to the deeds of their hands. (Jeremiah 25:6-7, 14)
...the children of Israel have provoked Me... to anger by the work of their hands... (Jeremiah 32:30, cf. 44:8)
I will utter My judgments against them concerning all their wickedness, because they... bowed themselves to the works of their hands. (Jeremiah 1:16)
In that day... people's eyes will look to the Holy One of Israel, and... not to the altars, the work of their hands, and... what their fingers have made... (Isaiah 17:7-8, cf. 31:7; 37:19, Jeremiah 10:9)
 The work of a person's hands is his own doing, thus evil and falsity, and this can be clearly seen from the fact that it was for this reason that the Israelites were forbidden to built an altar or temple out of hewn stones, or to use an iron tool on those stones; for they symbolized the work of a person's hands:
If you make Me an altar of stones, you shall not build it of hewn stones; for if you use your chisel on it, you will profane it. (Exodus 20:25)
Joshua built... an altar of... stones, on which he did not use an iron tool. (Joshua 8:30-31)
The temple (at Jerusalem)...was built of whole stone, and no hammer or axe or any iron tool was heard... while it was being built. (1 Kings 6:7)
 Everything that the Lord does is likewise called the work of His hands, and these are His inherent attributes, which in themselves are goods and truths. As, for example, in the following places:
The works of (Jehovah's) hands are truth and judgment. (Psalms 111:7)
Your mercy, O Jehovah, endures forever; do not cease the works of Your hands. (Psalms 138:8)
Thus said Jehovah, the Holy One of Israel, and his Maker: "Seek from Me signs concerning My children; concerning the work of My hands, command Me." (Isaiah 45:11)
Your people are all just..., the offshoot of My planting, the work of My hands... (Isaiah 60:21)
...O Jehovah, You are our Father, we are the clay, and You our potter, and all we the work of Your hands. (Isaiah 64:8)
