It is easier for a camel to go through a needle's eye, etc. This is a strong hyperbolic proverbial expression to represent anything that is very difficult to do. Dr. John Lightfoot, in his Hebrew exercitations upon St.
Matthew's Gospel. He quotes instances from the binical writings of a very similar phrase intended to represent something that is possible. For example, he quotes one rabbi disputing with another, who says, "Perhaps thou art one of those who can make an elephant pass through the eye of a needle; that is, "who speak things that are impossible.'
St. Jerome says," It is not the absolute impossibility of the thing which is set forth, but the infrequency of it."
