Terah
Terah is the father of Abram and the head of the household that leaves Ur of the Chaldees. The pieces of his life are gathered in a single chapter of Genesis, with two later texts — one historical, one genealogical — adding the verdict on his religion and his place in the line that runs to Christ.
The Generations of Terah
The genealogy steps down from Nahor to Terah, then names the three sons by whom Terah's line will branch: "And Nahor lived nine and twenty years, and begot Terah" (Gen 11:24), and "And Terah lived seventy years, and begot Abram, Nahor, and Haran" (Gen 11:26). The narrative is then explicitly opened as Terah's own toledot — "Now these are the generations of Terah. Terah begot Abram, Nahor, and Haran. And Haran begot Lot" (Gen 11:27). Loss strikes one branch immediately: "And Haran died before his father Terah in the land of his nativity, in Ur of the Chaldees" (Gen 11:28). Abram and Nahor marry, but the future of the line is already in question — "And Sarai was barren; She had no child" (Gen 11:30).
The Departure from Ur
Terah, not Abram, is the one who initiates the move out of Mesopotamia: "And Terah took Abram his son, and Lot the son of Haran, his son's son, and Sarai his daughter-in-law, his son Abram's wife; and he had them go out from Ur of the Chaldees, to go into the land of Canaan; and they came to Haran, and dwelt there" (Gen 11:31). The destination is Canaan, but the journey halts in Haran, and Terah dies there: "And the days of Terah were two hundred and five years: and Terah died in Haran" (Gen 11:32).
Beyond the River
Joshua's farewell speech at Shechem looks back across the same migration, but with a religious verdict attached. Terah is not described as a worshipper of Yahweh: "And Joshua said to all the people, This is what Yahweh, the God of Israel, says, Your⁺ fathers dwelt of old time beyond the River, even Terah, the father of Abraham, and the father of Nahor: and they served other gods" (Josh 24:2). The man who began the trek to Canaan belonged, in his own person, to the world that was being left behind.
In the Genealogy of Jesus
The line that began with Terah is preserved at the far end of the canon: "the [son] of Jacob, the [son] of Isaac, the [son] of Abraham, the [son] of Terah, the [son] of Nahor," (Luke 3:34). The man who served other gods stands, four generations before Abraham's grandson, in the descent of the Christ.
