Pseudo-Jerome — as excerpted in the Catena Aurea on Mark 9:14-29

“But there is no peace for man under the sun; envy is ever slaying the little ones, and lightnings strike the tops of the great mountains. Of all those who run to the Church, some as the multitudes come in faith to learn, others, as the Scribes, with envy and pride. It goes on, And straightway all the people, when they beheld Jesus, were greatly amazed, and feared.”
