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.

10356. 'Surely you shall keep My sabbaths' means thought which is holy and goes on unceasingly regarding the union of Divinity itself to the Lord's Human. This is clear from the meaning of 'sabbaths' in the highest sense as the union of Divinity itself to the Divine Human within the Lord, and in the relative sense as the joining of the Lord's Divine Human to heaven and also the joining of heaven to the Church, and in general - with those who constitute the Church, or with whom the Church exists - as the joining together of goodness and truth (regarding that union and these joinings together, that they are meant by 'sabbaths', see 8495, 8510, 8890, 8893, 9274); and from the meaning of 'surely (or altogether) keeping' as thinking about something in a holy way and unceasingly, for when the word 'keeping' has regard to the realities that were represented in that Church, thinking about the realities that were represented, keeping them in mind, and cherishing them in a holy way, are meant. For representatives were outward things which embodied inner realities and which for this reason provided people with the opportunity to think about inner realities. This explains why 'keeping Jehovah's sabbaths' means thinking in a holy manner and constantly about the Lord and the union of Divinity itself to His Divine Human, about the joining of the Lord's Divine Human to heaven and the joining of heaven to the Church, and about the joining together of goodness and truth within the person belonging to the Church. Since these are the actual essential realities of the Church - for without the acknowledgement of these and belief in them the Church is not the Church - statements about the sabbath, by which those realities are meant, is talked about last, and again and again furthermore to the end of the chapter.
