“Be careful that you don't practice your religion in front of people to draw their attention. If you do, you will have no reward from your Father who is in heaven.
References for Matthew 6:1
“Whenever you give to the poor, don't blow your trumpet as the hypocrites do in the synagogues and in the streets so that they may get praise from people. I assure you, that's the only reward they'll get.
But when you give to the poor, don't let your left hand know what your right hand is doing
so that you may give to the poor in secret. Your Father who sees what you do in secret will reward you.
