Hilary of Poitiers
Catena Aurea · Matthäusevangelium 13
Jesus saith unto them, Have ye understood all these things? They say unto him, Yea, Lord. Then said he unto them, Therefore every Scribe which is instructed unto the kingdom of heaven is like unto a man that is an householder, which bringeth forth out of his treasure things new and old.
Speaking to His disciples, He calls them Scribes on account of their knowledge, because they understood the things that He brought forward, both new and old, that is from the Law and from the Gospels; both being of the same householder, and both treasures of the same owner. He compares them to Himself under the figure of a householder, because they had received doctrine of things both new and old out of His treasury of the Holy Spirit.
