Finally it was determined that they should set a spy over them, and watch an opportunity when they had made a sally upon another tribe, and left their citadel unguarded. Some companies of able warriors and experienced troops were sent, that they might conceal themselves in the recesses of the mountain. At night, when the robbers were returned, jaded with their march and laden with spoil, and had stripped themselves of their armor, and deposited their plunder, the foremost enemy they had to encounter was sleep. Now that the first watch of night was gone:--"the disc of the sun was withdrawn into a shade, and Jonas had stepped into the fish's mouth "--the bold-hearted warriors sprang from their ambush and secured the robbers by pinioning them one after another. In the morning they presented them at the royal tribunal, and the king gave an order to put the whole to death. There happened to be among them a stripling, the fruit of whose early spring was ripening in its bloom, and the flower-garden of his cheek shooting into blossom. One of the vizirs kissed the foot of the imperial throne, and laid the face of intercession on the ground, and said, "This boy has not yet tasted the fruit of the garden of life, nor enjoyed the fragrance of the flowers of youth: such is my confidence in the generous disposition of his Majesty that it will favor a devoted servant by sparing his blood." The king turned his face away from this speech; as it did not accord with his lofty way of thinking, he replied:--"The rays of the virtuous cannot illuminate such as are radically vicious; to give education to the worthless is like throwing walnuts upon a dome:--it were wiser to eradicate the tree of their wickedness, and annihilate their tribe; for to put out a fire and leave the embers, and to kill a viper and foster its young, would not be the acts of rational beings. Though the clouds pour down the water of vegetation, thou canst never gather fruit from a willow twig. Exalt not the fortune of the abject, for thou canst never extract sugar from a mat or common cane."
