That golden devil A worm, a gnat, a fly, a hair, a seed of a raison, a skin of a grape Re: A Cabinet of Jewels, Chapters one and two
An angel on the outside—and a devil within

(Thomas Brooks, "A Cabinet of Choice Jewels" 1669)

"Hypocrites! You are so careful to clean the outside
 of the cup and the dish; but inside you are filthy—
 full of greed and self-indulgence!" Matthew 23:25

A hypocrite's outside never corresponds with his inside.
A hypocrite's outside is one thing—and his inside another.
A hypocrite's outside is religious—but his inside is wicked.

Hypocrites are like the Egyptian temples, which were beautiful
outside—but within there was nothing to be found but serpents
and crocodiles, and other venomous creatures. They are like
white silver—but they draw black lines. They have a seeming
sanctified outside—but are stuffed within with malice, pride,
worldliness, envy, etc. They are like window cushions, made up
of velvet and richly embroidered—but stuffed within with hay.

A hypocrite . . .
  may offer sacrifice with Cain,
  and fast with Jezebel,
  and humble himself with Ahab,
  and lament with the tears of Esau,
  and kiss Christ with Judas,
  and follow Christ with Demas,
  and be baptized with Simon Magus;
and yet for all this, his inside is as bad as any of theirs!

A hypocrite is . . .
  a Jacob on the outside—and an Esau within;
  a David on the outside—and a Saul within;
  a John on the outside—and a Judas within;
  a saint on the outside—and a Satan within;
  an angel on the outside—and a devil within.

But let all such hypocrites know, that pretend sanctity
is double iniquity—and accordingly at last they shall be
dealt with. "You snakes! You brood of vipers! How will
you escape being condemned to hell?" Matthew 23:33
