Jerome
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.
Or the Apostles are called Scribes instructed, as being the Saviour’s notaries who wrote His words and precepts on fleshly tables of the heart with the sacraments of the heavenly kingdom, and abounded in the wealth of a householder, bringing forth out of the stores of their doctrine things new and old; whatsoever they preached in the Gospels, that they proved by the words of the Law and the Prophets. Whence the Bride speaks in the Song of Songs; I have kept for thee my beloved the new with the old. (c. 7:13.)
