Hypocrite
An hypocrite is like unto an apple, that is very faire and beautiful without, but within is corrupted and rotten.
—Anthonie Fletcher (Certain Very Proper and Profitable Similes, 1595)
Hypocrites! for ye are like unto whited sepulchres, which indeed appear beautiful outward, but are within full of dead men’s bones, and of all uncleanness.
—New Testament
