and said to him, Depart from thy native country and from thy kindred, and come into the country which I shall shew thee. Then he came out of the land of the Chaldeans, and dwelt in Charran: and from thence, after his father died, He removed him into this land in which ye now dwell: though He gave him no inheritance in it, no not the breadth of a foot; but He promised to give it to him for a possession, even to his seed after him; though he had then no child." read more.
