Genesis 26:1-6

There was another famine in the land in addition to the one that had occurred in Abraham’s time. And Isaac went to Abimelech, king of the Philistines, at Gerar. The LORD appeared to him and said, “Do not go down to Egypt. Live in the land that I tell you about; stay in this land as a foreigner, and I will be with you and bless you. For I will give all these lands to you and your offspring, and I will confirm the oath that I swore to your father Abraham. I will make your offspring as numerous as the stars of the sky, I will give your offspring all these lands, and all the nations of the earth will be blessed by your offspring, because Abraham listened to My voice and kept My mandate, My commands, My statutes, and My instructions.” So Isaac settled in Gerar.
