OT Pts to consider on Gen.12:1-4

I keep going back to Gerald Janzen's little commentary on Abraham and all the Families of the Earth (Gen.12-50).Abram means father is exalted or perhaps on high.
Abram leaves from Haran, in modern Turkey, where his father had settled on his way to Canaan from the ancient city of Ur in southeastern Iraq of our time.. It is an ancient city. It s distance to  Shechem would be about 400 miles.
Quite simply he is told to go and will  both receive and be a blessing to all the families of the earth.The curse part usually gets deleted in church discussions.The word qll in Hebrew carries  a sense of belittling, making small, the opposite of the great name promised. Janzen notes seven verbs in total in this divine human relationship.
This then could be a good place to speak of the imperative of a call and its mysterious nature as well.
I realize that the patriarchal ages are fairly extended, but nothing compared to the primeval ages. If one chose then Abram is middle-aged given his life span, or we could go with the age given. either way, we could discuss the impact of a major move at middle age or as an elderly person. for instance, it just hit me that every person int he assisted living center where I just did a bible study had made a move, local or some distance, to be there.
Lot, his nephew is mentioned twice in the setting out. why is that do you think?Lot means to be covered, veiled.

I think it fruitful to consider noticing how we moved from the primeval history, a high altitude view, to an intense focus on one family now.

We could look at how Abram is continuing the unfinished journey of his father Terah. recall how the second President bush sought to continue the work of his father in Iraq, especially after agents sought to assassinate the elder Presdient Bush. Terah could mean ibex, or a wanderer, or some who who delays, loiters, or a moon god,depending on how to work with the letters and vowels and language roots.

blessing means what, then and now? In our time how does one bless or receive a blessing. Can it mean our current preoccupation with it meaning any good thing as in many religious argot?
