2-kings 20:7

Take a lump of figs - and laid it on the boil - We cannot exactly say in what Hezekiah's malady consisted. שחין shechin signifies any inflammatory tumour, boil, abscess, etc. The versions translate it sore, wound, and such like. Some think it was a pleurisy; others, that it was the plague; others, the elephantiasis; and others, that it was a quinsey. A poultice of figs might be very proper to maturate a boil, or to discuss any obstinate inflammatory swelling. This Pliny remarks, Omnibus quae maturanda ant discutienda sunt imponuntur. But we cannot pronounce on the propriety of the application, unless we were certain of the nature of the malady. This, however was the natural means which God chose to bless to the recovery of Hezekiah's health; and without this interposition he must have died.

A lump of figs - The usual remedy in the East, even at the present day, for ordinary boils. But such a remedy would not naturally cure the dangerous tumor or carbuncle from which Hezekiah suffered. Thus the means used in this miracle were means having a tendency toward the result performed by them, but insufficient of themselves to produce that result (compare 2 Kings 4:34 note).
