Genesis 26:2-5

2And the LORD appeared to him, and said, Go not down into Egypt; dwell in the land which I shall tell thee of: 3Sojourn in this land, and I will be with thee, and will bless thee; for to thee, and to thy seed, I will give all these countries, and I will perform the oath which I swore to Abraham thy father; 4And I will make thy seed to multiply as the stars of heaven, and will give to thy seed all these countries; and in thy seed shall all the nations of the earth be blessed; 5Because that Abraham obeyed my voice, and kept my charge, my commandments, my statutes, and my laws.
