Genesis 26:26-31

Then Abimelech came to him from Gerar with Ahuzzath his advisor and Phicol the head of his troops. Isaac asked them, “Why did you come to me? You hate me; you threw me out of your country.” They said, “We’ve realized that GOD is on your side. We’d like to make a deal between us—a covenant that we maintain friendly relations. We haven’t bothered you in the past; we treated you kindly and let you leave us in peace. So—GOD’s blessing be with you!” Isaac laid out a feast and they ate and drank together. Early in the morning they exchanged oaths. Then Isaac said good-bye and they parted as friends.
