Moreover when you fast, be not, as the hypocrites, of a sad countenance: for they disfigure their faces, that they may appear unto men to fast. Verily I say unto you, They have their reward.
All Commentaries on Matthew 6:16 Go To Matthew 6
Jerome
AD 420
The word, “exterminare,” so often used in the ecclesiastical Scriptures thougha blunder of the translators, has a quite different meaning from that in which it is commonly understood. It is properly said of exiles who are sent beyond the boundry of their country. Instead of this word, it would seem better to use the word, “demoliri,” ‘to destroy,’ in translating the Greek . The hypocrite destroys his face, in order that he may feign sorrow, and with a heart full of joy wears sorrow in his countenance.
