Nimrod tried to kill Abraham for speaking out against his ruling cult, but Abraham was miraculously saved. Then G-d told him to leave the land of his birth and to travel to "a land which I shall show you." This was the land of Israel, the Holy Land, which G-d gave to Abraham and his descendants as an inheritance, as a place in which to keep all of His commandments in the Torah and thus to be close to Him.
===Abraham studied at the academy of Shem and Eber===
There Abraham studied at the academy of Shem and Eber, and he acquired great wisdom. He traveled with his wife and his flocks and herds, offering hospitality to people and discussing the concepts of divinity with them, each according to his level. Sarah, meanwhile, instructed the women. Abraham wrote books and devoted all his wealth to doing kindness to everyone who needed it. He brought others to the understanding of the the Seven Laws, by which he himself was bound, but his efforts for the spreading of this awareness earned him a much higher reward; his descendants were to be given the privilege of keeping the whole Torah in the Jewish manner.
