This is precisely the image Jesus uses when He speaks of the “eye of the needle.” Tradition holds that this phrase is in reference to a small gate that required a camel (or other pack animal) laden with goods to be unencumbered in order to pass through.

There has never existed in all of history a gate in Jerusalem called the "eye of the needle." This interpretation was made up by some rich prick in the 11th century and repeated by other rich pricks through to the modern day in order to avoid the uncomfortable truth that Jesus said in no uncertain terms that they weren't getting into heaven.
