Genesis 27:39-40

Then his father Isaac said to him, “I’m telling you that you and the people born into your family later on, you will live in a place where the ground is dry. God won’t send any water to wet that land, and there won’t be any good food plants growing there. Your tribe will always fight and steal from other people to get their food. Your brother’s tribe will be boss over your tribe. But one day, your tribe will fight back, and then your brother’s tribe will not be boss over your tribe any more.”
