Genesis 26:28-30

28They said, "We see plainly that the Lord has been with you. So we said, let there be a sworn pact between us, between you and us, and let us make a covenant with you,

29that you will do us no harm, just as we have not touched you and have done to you nothing but good and have sent you away in peace. You are now the blessed of the Lord."

30So he made them a feast, and they ate and drank.
