Genesis 26:2-5

The LORD appeared to Isaac and said, “Do not go down to Egypt, but do as I tell you. Live here as a foreigner in this land, and I will be with you and bless you. I hereby confirm that I will give all these lands to you and your descendants, just as I solemnly promised Abraham, your father. I will cause your descendants to become as numerous as the stars of the sky, and I will give them all these lands. And through your descendants all the nations of the earth will be blessed. I will do this because Abraham listened to me and obeyed all my requirements, commands, decrees, and instructions.”
