Genesis 17:7-8

7 My covenant with you is very strong. I am making it with you and with your descendants. It will continue for generation after generation of your descendants, for all time. I will be your God. I will also be the God of all your descendants. 8 You are now living here in Canaan as a foreign person. But I will give all of this land to you and to your descendants. It will belong to them for ever. I will be their God.’
