Origen, on Prov 22:28

“Pass not beyond the ancient bounds which thy fathers have set.”

“Nonetheless, it is clear that many examples, which we never read in those Scriptures that we deem canonical but nonetheless are found in the apocryphal books and are shown clearly to have been taken from them, have been brought forth and inserted into the New Testament either by the apostles or the Evangelists. But we must not give credence to the apocryphal books even in this way, for the eternal boundaries, which our fathers erected, must not be moved. It could be that the apostles or the Evangelists, filled with the Holy Spirit, knew what had to be taken from those writings and what had to be refuted. But it is not for us to presume some such ability without danger, when we do not have such abundance of the Spirit.”
