Hezekiah prayed and received God's promise
of healing. Isaiah told him to place a poultice
of figs on the boil, but it didn't have any heal-
ing value.

It was a test of Hezekiah's obedience, the
same as Naaman was to dip seven times in
the Jordan.

Any means ever used in the Bible had no
healing virtue whatever, but were used as
a test of faith and obedience.
