Remigius of Auxerre
Catena Aurea · Matthäusevangelium 1
So all the generations from Abraham to David are fourteen generations; and from David until the carrying away into Babylon are fourteen generations; and from the carrying away into Babylon unto Christ are fourteen generations.
He made fourteen generations, because the ten denotes the decalogue, and the four the four books of the Gospel; whence this shews the agreement of the Law and the Gospel. And he put the fourteen three times over, that he might shew that the perfection of law, prophecy, and grace, consists in the faith of the Holy Trinity.
