1And there was a famine in the land, beside the first famine that was in the days of Abraham. And Isaac went unto Abimelech king of the Philistines unto Gerar.

2 And the Lord appeared unto him, and said, Go not down into Egypt; dwell in the land which I shall tell thee of:

3 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;

4 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;

5 Because that Abraham obeyed my voice, and kept my charge, my commandments, my statutes, and my laws.
