Genesis 26:1-6

Now there was a time of hunger in the land, besides the time of hunger that happened during Abraham’s life. So Isaac went to the town of Gerar to see Abimelech king of the Philistines. The LORD appeared to Isaac and said, “Don’t go down to Egypt, but live in the land where I tell you to live. Stay in this land, and I will be with you and bless you. I will give you and your descendants all these lands, and I will keep the oath I made to Abraham your father. I will give you many descendants, as hard to count as the stars in the sky, and I will give them all these lands. Through your descendants all the nations on the earth will be blessed. I will do this because your father Abraham obeyed me. He did what I said and obeyed my commands, my teachings, and my rules.” So Isaac stayed in Gerar.
