Hello PB, Turretin writes on pages 81-82 in vol. 1 of his Institutes: "The difficulty consists in this: that Moses says that Abram was in the seventieth year of Terah (Gen. 11:26), and Stephen expressly asserts that Abraham removed from Haran to Canaan after the death of Terah (Acts 7:4). Now it is plain from Gen. 12:4 that Abraham departed from Haran in his seventy-fifth year, and his father Terah lived to the age of two hundred and five years (Gen. 11:32)" Later in the page, he says that others solved the difficulty right: "They maintain that there were two calls of Abram: the first from Ur of Chaldees to Haran, his father being alive and in his 145th year, and Abraham in his seventy-fifth (of which Moses speaks, Gen 11:31;12:1). But the other (after the death of his father) from Haran to Canaan with appears to be intimated in Gen.12:4, 5. Stephen indeed plainly refers to this when he says "Abraham called of God came out of the land of the Chaldeans, and dwelt in Haran; and afterwards and from thence, when his father was dead, he removed him in Cananna" (Acts 7:4) Here God is said to have called him twice: first from Ur of the Chaldees to Hara; afterward from Haran to Canaan. This seems to be a fit and easy solution of the difficulty." So Turretin says the first call from Ur to Haran was when Abraham was in his 75th year (Terah then 145 years old). And then Abram departed Haran at the second call after the death of his father (205 years old). Does this reconcile Acts 7:4 and Gen. 12:4? Any insights? Was Turretin successful in making his case? Thank you.
