C. F. Keil and Franz Delitzsch on 1 Chronicles 1:24-27

1Ch 1:24-27 The patriarchs from Shem to Abraham. - The names of these, again, are simply ranged in order according to Gen 11:10-26, while the record of their ages before the begetting and after the birth of sons is omitted. Of the sons of Terah only Abram is named, without his brothers; with the remark that Abram is Abraham, in order to point out to the reader that he was the progenitor of the chosen people so well known from Genesis (cf. 1Ch 1:27).
