Bereshis 12:1-4

Now HASHEM had said unto Avram, Get thee out of thy country, and from thy kindred, and from the bais avicha, unto ha'aretz that I will show thee; So that I will make of thee a goy gadol (great nation), so that I will bless thee, and make thy shem great; and so thou shalt be a brocha (blessing); And I will bless the one blessing you, and curse him that curses you; and kol mishpochot haadamah shall be blessed through you. So Avram departed as HASHEM had told him; and Lot went with him; and Avram was seventy and five years old when he departed out of Charan.
