Terah was part of this migration. He took his son Abraham and his grandson Lot and their wives and left Ur of the Chaldees to go to Canaan, but when they arrived at Harran they settled there (Gen 11,31). But God did not let the matter rest there. God inaugurated anew God’s purpose in the world through the calling of Abram and making him Abraham (Gen 12,1). Thus began a history initiated by God and uniquely related to God, a history that is meant to be both model and agent of God’s relationship with humankind.
