“God said to Abram, 'Go away from your land, from your birthplace, and from your father's house, to the land that I will show you....'”
Why is this idea repeated three times? We have discussed here, here, and here that the forefathers, and especially Abraham, embody the five spiritual entities of our world, who are in turn influenced by Abraham's deeds. These entities are hidden and imperceptible, and they further hide within each other, but they are the ways of God's interaction with the physical world.
Kindness (Chesed), which Abraham represents, has three foundations. The lowest of them is Victory (Netzach), which can be also translated as Eternity, and it corresponds to “your land,” because it is the closest to Rulership, representing the land and the female.
The next, higher level of Kindness is called “your birthplace,” because it is hidden in the so-called mouth, opening, of the 'ever', member, denoted by the letters A-V-R of Abraham's name", and is connected to birth. “Your father's house” is a hint to Wisdom, and to the Supernal Father.
In the beginning of Abraham's life the spiritual image of Cosmic Man, or Zeir Anpin, was young, and his brain was not fully developed. Therefore, Abraham was causing supernal unions solely through his Kindness. However, as Abraham's life progressed, he caused the Cosmic Man to mature and acquire Wisdom. Abraham is the forefather who is connected with Kindness, and kindness has the quality of never deteriorating as it descends through the spiritual worlds. This caused him to receive an additional letter “hei” in his name, whereas Isaac and Jacob did not additional letters.
