David had four hundred young men, handsome in appearance and with their
hair cut close upon their foreheads, but with long flowing curls behind,
who used to ride in chariots of gold at the head of the army. These were
men of power (men of the fist, in the original), the mighty men of the
house of David, who went about to strike terror into the world.
THE TALMUD, _Kiddushin_, fol. 76, col. 2.
