Genesis 26:2-5

And the Lord came to him in a vision and said, Do not go down to Egypt; keep in the land of which I will give you knowledge: Keep in this land, and I will be with you and give you my blessing; for to you and to your seed will I give all these lands, giving effect to the oath which I made to your father Abraham; I will make your seed like the stars of heaven in number, and will give them all these lands, and your seed will be a blessing to all the nations of the earth; Because Abraham gave ear to my voice and kept my words, my rules, my orders, and my laws.
