He
then
immediately
obtained
permission
from
the
King
to
undertake
[to
teach]
in
the
savage
regions
of
the
Medians
who
were
difficult
to
communicate
with,
not
only
because
of
their
devilish,
satanic,
and
fiendish
character,
but
also
because
of
their
very
crude,
corrupt,
and
harsh
language.
Undertaking
to
refine
them,
they
made
them,
offsprings
of
many
generations,
intelligible,
eloquent,
educated,
and
informed
of
godly
wisdom.
Thus
they
became
immersed
in
the
laws
and
commandments,
to
the
extent
of
becoming
distinguishable
from
their
fellow
natives.
