We will now turn to the metaphor of the Camel and the needle's eye. Of course it can be taken merely as a very bold metaphor, but it may also be understood in a simpler sense, the sense in which it was probably understood by those who heard it. In Oriental cities, there are in the large gates small and very low apertures called metaphorically "needle's-eyes," just as we talk of certain windows as "bull's-eyes." These entrances are too narrow for a Camel to pass through them in the ordinary manner, especially if loaded. When a laden Camel has to pass through one of these entrances, it kneels down, its load is removed, and then it shuffles through on its knees. "Yesterday," writes Lady Duff-Gordon from Cairo, "I saw a camel go through the eye of a needle, _i.e._ the low-arched door of an enclosure. He must kneel, and bow his head to creep through; and thus the rich man must humble himself." There is another passage in which the Camel is used by our Lord in a metaphorical sense. This is the well-known sentence: "Ye blind guides, which strain at a gnat, and swallow a camel" (Matt. xxiii. 24). It is remarkable that an accidental misprint has robbed this passage of its true force. The real translation is: "which strain _out_ the gnat, and swallow the camel." The Greek word is διυλίζω, which signifies to filter thoroughly; and the allusion is made to the pharisaical custom of filtering liquids before drinking them, lest by chance a gnat or some such insect which was forbidden as food might be accidentally swallowed. THE BACTRIAN CAMEL. General description of the animal--Its use in mountain roads--Peculiar formation of the foot--Uses of a mixed breed--Its power of enduring cold--Used chiefly as a beast of draught--Unfitness for the plough--The cart and mode of harnessing--The load which it can draw--Camel-skin ropes--A Rabbinical legend. The second kind of Camel--namely, the Bactrian species--was probably unknown to the Jews until a comparatively late portion of their history. This species was employed by the Assyrians, as we find by the sculptures upon the ruins, and if in no other way the Jews would become acquainted with them through the nation by whom they were conquered, and in whose land they abode for so long. The Bactrian Camel is at once to be distinguished from that which has already been described by the two humps and the clumsier and sturdier form. Still the skeletons of the Bactrian and Arabian species are so similar that none but a very skilful anatomist can distinguish between them, and several learned zoologists have expressed an opinion, in which I entirely coincide, that the Bactrian and Arabian Camels are but simple varieties of one and the same species, not nearly so dissimilar as the greyhound and the bulldog.
