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.

709. The name Jehovah is used because now the subject is charity. From verse 9 to the end of the previous chapter Jehovah is not used but God, the reason being that there the subject is the preparation of Noah, or the member of the Church called Noah, as regards things of his understanding, which are matters of faith. Here however it is the preparation of him as regards the things of his will, which are matters of love. When the subject is the things of the understanding, that is, the truths of faith, the name God is used, but when it is those of the will, that is, goods stemming from love, Jehovah is used. For it is not things of the understanding, that is, of faith, that constitute the Church but those of the will which are matters of love. Jehovah is present within love and charity, but not within faith except faith that inheres in love or charity. This also is why in the Word faith is compared to the night, but love to the daytime, as in Genesis 1 where the great lights are mentioned; the greater light, which is the sun and means love, has dominion over the day, while the lesser light, which is the moon and means faith, has dominion over the night, Genesis 1:14, 16. Similarly in the Prophets, Jeremiah 31:35; 33:20; Psalms 136:8-9; also Revelation 8:12.
