When his father was dead (meta to apothanein auton). Meta with the accusative of the articular infinitive and the accusative of general reference (auton), regular Greek idiom. In Gen 11:32 it is stated that Terah died at Haran at the age of 205. There are various explanations of the discrepancy, but no one that seems certain. It is possible (Hackett, Felten) that Abraham is mentioned first in Gen 11:26 because he became the most prominent and was really younger than Haran his brother who died before the first migration who was really sixty years older than Abraham. According to this view Terah was 130 years old at the birth of Abraham, leaving Abraham 75 at the death of Terah (205).
Wherein ye now dwell (eis hēn humeis nun katoikeite). Note eis in the sense of en as often. Note also emphatic use of humeis (ye) and now (nun).
