Answer
The author to the Hebrews affirms the continued validity of the old covenant in a number of ways. There are a lot of quotations from the Old Testament, all of which point forward, of course, beyond themselves, but in a sense to fulfill and to bring to complete fruition the promises that are made there. So, in particular in chapter eight, for example, the quotation from-- the promise for the new covenant is given in a context in which there's an anticipation of looking forward, that actually the things that had been hoped for are now fulfilled in the coming of Christ.
