Mt 6:1-6,16-18
At that time, Jesus said to his disciples: ‘Be careful not to parade your uprightness in public to attract attention; otherwise you will lose all reward from your Father in heaven. So when you give alms, do not have it trumpeted before you; this is what the hypocrites do in the synagogues and in the streets to win human admiration. In truth I tell you, they have had their reward. But when you give alms, your left hand must not know what your right is doing; your almsgiving must be secret, and your Father who sees all that is done in secret will reward you.
