“Watch out! Don’t do your good deeds publicly, to be admired by others, for you will lose the reward from your Father in heaven. When you give to someone in need, don’t do as the hypocrites do—blowing trumpets in the synagogues and streets to call attention to their acts of charity! I tell you the truth, they have received all the reward they will ever get. But when you give to someone in need, don’t let your left hand know what your right hand is doing. Give your gifts in private, and your Father, who sees everything, will reward you.
“When you pray, don’t be like the hypocrites who love to pray publicly on street corners and in the synagogues where everyone can see them. I tell you the truth, that is all the reward they will ever get. But when you pray, go away by yourself, shut the door behind you, and pray to your Father in private. Then your Father, who sees everything, will reward you. — Mt 6:1-6
“And when you fast, do not look gloomy like the hypocrites, for they disfigure their faces that their fasting may be seen by others. Truly, I say to you, they have received their reward. — Mt 6:16
