John Chrysostom — as excerpted in the Catena Aurea on Mark 10:17-27

“(ubi sup.) Or else, after saying difficult, He then shews that it is impossible, and that not simply, but with a certain vehemence; and he shews this by an example, saying, It is easier for a camel to pass through the eye of a needle, than for a rich man to enter the kingdom of heaven.”
