Smith's Bible Dictionary

1. His grandfather; the son of Serug, and father of Terah. Gen 11:22-25. (B.C. 2174).

2. Grandson of Nahor, 1, son of Terah, and brother of Abraham and Haran. Gen 11:26-27. (B.C. 2000). The order of the ages of the family of Terah is not improbably inverted in the narrative; in which case, Nahor instead of being younger than Abraham, was really older. He married Milcah, the daughter of his brother, Haran; and when Abraham and Lot migrated to Canaan, Nahor remained behind in the land of his birth, on the eastern side of the Euphrates.
