The third trial was his migration from his father's house and from the land of his birth; and He brought him to Haran, and there his father Terah died, and Athrai his mother. Migration is harder for man than for any other creature. Whence do we know of his migration? Because it is said, "Now the Lord said || unto Abram, Get thee out" (Gen. 12:1).
The fourth trial (was the famine). From the day when the heavens and the earth were created, the Holy One, blessed be He, had not brought into the world a famine but only in the days of Abraham, and not in any of the lands but only in the land of Canaan, in order to try him and to bring him down into Egypt, as it is said, "And there was a famine in the land, and Abram went down into Egypt" (Gen. 12:10).
