Abraham the father of a multitude, son of Terah, named (Gen. 11:27) before his older brothers Nahor and Haran, because he was the heir of the promises. Till the age of seventy, Abram sojourned among his kindred in his native country of Chaldea. He then, with his father and his family and household, quitted the city of Ur, in which he had hitherto dwelt, and went some 300 miles north to Haran, where he abode fifteen years. The cause of his migration was a call from God (Acts 7:2-4). There is no mention of this first call in the Old Testament; it is implied, however, in Gen. 12. While they tarried at Haran, Terah died at the age of 205 years. Abram now received a second and more definite call, accompanied by a promise from God (Gen. 12:1,2); whereupon he took his departure, taking his nephew Lot with him, “not knowing whither he went” (Heb. 11:8). He trusted implicitly to the guidance of Him who had called him.
