Matthew 6:1-4

“And take care not to practice your righteousness before people to be seen by them; otherwise you have no reward from your Father who is in heaven. Therefore whenever you practice charitable giving, do not sound a trumpet in front of you, as the hypocrites do in the synagogues and in the streets, in order that they may be praised by people. Truly I say to you, they have received their reward in full! But you, when you practice charitable giving, do not let your left hand know what your right hand is doing, in order that your charitable giving may be in secret, and your Father who sees in secret will reward you.
