Genesis 11:27

27.Terah begat Abram. Here also Abram is placed first among his brethren, not (as I suppose) because he was the firstborn; but because Moses, intent on the scope of his history, was not very careful in the arrangement of the sons of Terah. It is also possible that he had other sons. For, the reason why Moses speaks especially of them is obvious; namely, on account of Lot, and of the wives of Isaac and Jacob. I will now briefly state why I think Abram was not the first born. Moses shortly afterwards says, that Haran died in his own country, before his father left Chaldea, and went to Charran. (332) But Abram was seventy-five years old when he departed from Charran to dwell in the land of Canaan. (333) And this number of seventy-five years is expressly given after the death of Terah. Now, if we suppose that Abram was born in his father’s seventieth year, we must also allow that we have lost sixty years of Terah’s age; which is most absurd. (334) The conjecture of Luther, that God buried that time in oblivion, in order to hide from us the end of the world, in the first place is frivolous, and in the next, may be refuted by solid and convincing arguments. Others violently wrest the words to apply them to a former egress; and think that he lived together with his father at Charran for sixty years; which is most improbable. For to what end should they have protracted their stay so long in the midst of their journey? But there is no need of labourious discussion. Moses is silent respecting the age of Abraham when he left his own country; but says, that in the seventy-fifth year of his age, he came into the land of Canaan, when his father, having reached the two hundredth and fifth year of his life, had died. Who will not hence infer that he was born when his father had attained his one hundredth and thirtieth year? (335) But he is named first among those sons whom Terah is said to have begotten, when he himself was seventy years old. I grant it; but this order of recital does nothing towards proving the order of birth, as we have already said. Nor, indeed, does Moses declare in what year of his life Terah begat sons; but only that he had passed the above age before he begat the three sons here mentioned. Therefore, the age of Abraham is to be ascertained by another mode of computation, namely, from the fact that Moses assigns to him the age of seventy-five when his father died, whose life had reached to two hundred and five years. A firm and valid argument is also deduced from the age of Sarai. It appears that she was not more than ten years younger than Abraham. If she was the daughter of his younger brother, she would necessarily have equalled her own father in age. (336) They who raise an objection, to the effect that she was the daughter-in-law, or only the adopted daughter of Nahor, produce nothing beyond a sheer cavil.
