Genesis 26:28-31

28And they said, We saw certainly that Yhwh was with thee: and we said, Let there be now an oath betwixt us, even betwixt us and thee, and let us make a covenant with thee;1

29That thou wilt do us no hurt, as we have not touched thee, and as we have done unto thee nothing but good, and have sent thee away in peace: thou art now the blessed of Yhwh.2

30And he made them a feast, and they did eat and drink.

31And they rose up betimes in the morning, and sware one to another: and Isaac sent them away, and they departed from him in peace.
