Genesis 26:26-29

26Abimelech, his friend Ahuzzath, and Phicol, the commander of his army, came from Gerar to see Isaac.

27Isaac asked them, “Why have you come to me, since you hate me and sent me away from you?”

28They answered, “We have seen that the Lord is with you. So we thought, ‘There should be a solemn agreement between us.’ We’d like to make an agreement with you

29that you will not harm us, since we have not touched you. We have done only good to you and let you go in peace. Now you are blessed by the Lord.”
