A
Hypocrite
is,
One who pretends to be
what he is not;
"One who has the form of godliness without the power, or who
assumes the appearance of
piety and virtue, when
he
is destitute of
true religion."
Webster's
1828   
And when thou prayest,
thou shalt not be as the hypocrites are:
for they love to pray standing in the synagogues and in the corners of the streets, that they may be seen of men.
Verily I say unto you,
They have their reward.

  Matthew   
6:5
