Genesis 26:5

Sojourn in this land, and I will be with thee, and will bless thee; for unto thee, and unto thy seed, I will give all these countries, and I will perform the oath which I sware unto Abraham thy father;

And I will make thy seed to multiply as the stars of heaven, and will give unto thy seed all these countries; and in thy seed shall all the nations of the earth be blessed;

And Isaac dwelt in Gerar:

And the men of the place asked [him] of his wife; and he said, She [is] my sister: for he feared to say, [She is] my wife; lest, [said he], the men of the place should kill me for Rebekah; because she [was] fair to look upon.
