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.

3616. 'And I send and fetch you from there' means that at that point the end in view has been reached. This is clear from what comes before and after; for the end in view, meant here by 'sending and fetching you from there', is reached when truth accords with good, and in that way truth has been made subject to good, and is subservient to it. This end, following Jacob's stay with Laban, is represented by the occasion when Esau ran to meet Jacob, and embraced him, and fell on his neck, and kissed him, and they wept, Genesis 33:4. For when the end in view, which is conjunction, is reached, the good of the rational flows into the good of the natural directly, and through the good of the natural into the truth there, as well as indirectly through the truth of the rational into the truth of the natural, and through the truth of the natural into the good there, 3573. From this it is evident why Rebekah, who represents the truth of the rational, said to Jacob, who represents the truth of the natural, 'I send and fetch you from there'.
