Genesis 26:26-29

26Later, Abimelech came to Isaac from Gerar, with Ahuzzath his adviser and Phicol the commander of his army.

27“Why have you come to me?” Isaac asked them. “You hated me and sent me away.”

28“We can plainly see that the LORD has been with you,” they replied. “We recommend that there should now be an oath between us and you. Let us make a covenant with you 29that you will not harm us, just as we have not harmed you but have done only good to you, sending you on your way in peace. And now you are blessed by the LORD.”
