Matthew 6:15-16

King James Version

¹⁵ But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.

¹⁶ Moreover when ye 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.
