An impossibility. The whole phrase, which comes from the Gospels of St. Matthew (19:24) and St. Mark (10:25), states that it is easier for a camel to go through the eye of a needle than for a rich man to enter into the Kingdom of God. Variants appear in both Jewish religious writings and in the Islamic Koran. The thought is repeated by Shakespeare in Richard II (5.5): “It is as hard to come as for a camel to thread the postern of a small needle’s eye.”
