Matthew 6:1-4

1 “Be careful that you don't do your charitable giving before men, to be seen by them, or else you have no reward from your Father who is in heaven.  2 Therefore when you do merciful deeds, don't sound a trumpet before yourself, as the hypocrites do in the synagogues and in the streets, that they may get glory from men. Most assuredly I tell you, they have received their reward.  3 But when you do merciful deeds, don't let your left hand know what your right hand does,  4 so that your merciful deeds may be in secret, then your Father who sees in secret will reward you openly.
