Matthew 6:1-4 New Revised Standard Version (NRSV)
6 “Beware of practicing your piety before others in order to be seen by them; for then you have no reward from your Father in heaven.
2 “So whenever you give alms, do not sound a trumpet before you, as the hypocrites do in the synagogues and in the streets, so that they may be praised by others. Truly I tell you, they have received their reward. 3 But when you give alms, do not let your left hand know what your right hand is doing, 4 so that your alms may be done in secret; and your Father who sees in secret will reward you.[a]
