Bonaventure, on Gen 38:28

“This shall come forth the first.”

“Again, they are compared two by two: in the Old Testament, there are the times before the Law and under the Law; in the New, the times of the calling of the Gentiles and of the calling of the Israelites that shall be at the end. And these times are symbolized by the two sons of Juda, Zara and Phares. Now, Zara "put out a hand. The midwife took a scarlet thread," and "tied it on his hand. But he drew back his hand," and Phares was born, who opened the breach. The Jews believed at first, but they immediately drew back their hand at the time of the early Church; but after all of the Gentiles have come in, then Zara will be born and the Jewish people will be converted.”
