Take a lump of figs Though the deliverance was certainly promised, yet means must be used, and those suitable. The figs would help to ripen the bile, and bring it to a head, that the matter of the disease might be discharged that way. This means, however, would have been altogether insufficient of itself to effect so sudden and complete a cure, without the co-operation of the divine power, to which the king's restoration to health is chiefly to be ascribed.
