Catena Aurea · Matthäusevangelium 2
Then Herod, when he saw that he was mocked of the wise men, was exceeding wroth, and sent forth, and slew all the children that were in Bethlehem, and in all the coasts thereof, from two years old and under, according to the time which he had diligently enquired of the wise men.
(Gloss. ord.) Or because he feared that the Child to whom even stars ministered, might transform His appearance to greater or under that of His own age, or might conceal all those of that age: hence it seems to be that he slew all from one day to two years old.
