SEV Biblia, Chapter 11:26
Y vivió Taré setenta años, y engendró a Abram, y a Nacor, y a Harán.
Clarke's Bible Commentary - Genesis 11:26
Verse 26. And Terah lived seventy years, and begat Abram, Nahor, and Haran.] Haran was certainly the eldest son of Terah, and he appears to have been born when Terah was about seventy years of age, and his birth was followed in successive periods with those of Nahor his second, and Abram his youngest son. Many have been greatly puzzled with the account here, supposing because Abram is mentioned first, that therefore he was the eldest son of Terah: but he is only put first by way of dignity.An in stance of this we have already seen, chap. v. 32, where Noah is represented as having Shem, Ham, and Japheth in this order of succession; whereas it is evident from other scriptures that Shem was the youngest son, who for dignity is named first, as Abram is here; and Japheth the eldest, named last, as Haran is here. Terah died two hundred and five years old, ver. 32; then Abram departed from Haran when seventy-five years old, chap. xii. 4; therefore Abram was born, not when his father Terah was seventy, but when he was one hundred and thirty. When any case of dignity or pre-eminence is to be marked, then even the youngest son is set before all the rest, though contrary to the usage of the Scriptures in other cases. Hence we find Shem, the youngest son of Noah, always mentioned first; Moses is mentioned before his elder brother Aaron; and Abram before his two elder brethren Haran and Nahor. These observations are sufficient to remove all difficulty from this place.
Matthew Henry Commentary
Verses 10-26 - Here is a genealogy, or list of names, ending in Abram, the friend of God, and thus leading towards Christ, the promised Seed, who was the son of Abram. Nothing is left upon record but their names and ages; the Holy Ghost seeming to hasten through them to the history of Abram. Ho little do we know of those that are gone before us in this world, eve of those that lived in the same places where we live, as we likewis know little of those who now live in distant places! We have enough to do to mind our own work. When the earth began to be peopled, men' lives began to shorten; this was the wise disposal of Providence.
