Genesis 26:28-30

28They answered, “We saw clearly that the Lord was with you; so we said, ‘There ought to be a sworn agreement between us’—between us and you. Let us make a treaty with you

29that you will do us no harm, just as we did not harm you but always treated you well and sent you away peacefully. And now you are blessed by the Lord.”

30Isaac then made a feast for them, and they ate and drank.
