The full quote is attributed to Jesus - "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". On the face of it, it seems to be a ridiculous statement. However there is a gateway into the city of Jerusalem called ' The eye of the needle', and it is particularly narrow and difficult to negotiate. It is not impossible to lead a camel through this gateway, but it does require a fair bit of careful manoeuvering and persuasion for the camel to pass through the gateway.
