Bede the Venerable, on Matt 2:16

“Then Herod perceiving that he was deluded by the wise men, was exceeding angry; and sending killed all the men children that were in Bethlehem, and in all the borders thereof, from two years old and under, according to the time which he had diligently inquired of the wise men.”

“(Hom. in Nat. Innocent.) In this death of the children the precious death of all Christ’s martyrs is figured; that they were infants signifies, that by the merit of humility alone can we come to the glory of martyrdom; that they were slain in Bethlehem and the coasts thereof, that the persecution shall be both in Jerusalem whence the Church originated, and throughout the world; in those of two years old are figured the perfect in doctrine and works; those under that age the neophytes; that they were slain while Christ escaped, signifies that the bodies of the martyrs may be destroyed by the wicked, but that Christ cannot be taken from them.”
