Bereshis 35:11-12

And Elohim said unto him, I am El Shaddai; be fruitful and multiply; a Goy (nation) and a Kehal Goyim shall be from thee, and Melechim shall come out of thy loins; And HaAretz which I gave Avraham and Yitzchak, to thee I will give it, and to thy zera after thee will I give HaAretz.
