The Needle's Eye.

“ON my return to the city (Hebron) with my two Jewish guides, we entered it further to the north than the side from which we had begun our walk. We were proceeding through a double gateway, such as is seen in so many of the old Eastern cities, even in some of the modern, one wide arched road, and another narrow one by the side, through the latter of which persons on foot generally pass to avoid the chance of being jostled or crushed by the beasts of burthen coming through the main gateway.
We met a caravan of loaded camels thronging the passage. The drivers cried out to my two companions and myself, desiring us to betake ourselves for safety to the gate with the smaller arch, calling it ‘Es Summel Kayût,’ the hole or eye of the needle. This entrance gate is low and narrow. The sumpter camel cannot be made to pass through it unless with great difficulty, and stript of all the encumbrance of his load, his trappings, and his merchandise.” —Lands Classic and Sacred.
