Pseudo-Chrysostom
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.
Having enumerated the generations from Abraham to Christ, he divides them into three divisions of fourteen generations, because three times at the end of fourteen generations the state of the people of the Jews was changed. From Abraham to David they were under Judges; from David to the carrying away into Babylon under Kings; from the carrying away to Christ under the High Priests. What he would shew then is this; like as ever at the end of fourteen generations the state of men has changed, so there being fourteen generations completed from the carrying away to Christ, it must needs be that the state of men be changed by Christ. And so since Christ all the Gentiles have been made under one Christ Judge, King, and Priest. And for that Judges, Kings, and Priests prefigured Christ’s dignity, their beginnings were always in a type of Christ; the first of the Judges was Joshua the son of Nave; the first of the Kings, David; the first of the Priests, Jesus son of Josedech. That this was typical of Christ none doubts.
