Jerome — as excerpted in the Catena Aurea on Matthew 12:38-40

“They require a sign of Him, as though what they had seen were not signs; and in another Evangelist what they required is more fully expressed, We would see of thee a sign from heaven. Either they would have fire from heaven as Elias did; or after the example of Samuel they would that in summer-time, contrary to the nature of the climate, thunder should be heard, lightnings gleam, and rain descend; as though they could not have spoken falsely even against such miracles, and said that they befel by reason of divers hidden motions in the air. For if thou cavillest against what thou not only beholdest with thine eyes, but feelest with thine hand, and reapest the benefit of, what wilt thou do in those things which come down from heaven. You might make answer, that in Egypt the magi also had given many signs from heaven.”
