how about this:
Mt 6:1 "Take heed that you do not do your charitable deeds before
men, to be seen by them. Otherwise you have no reward from your
Father in heaven.
2 "Therefore, when you do a charitable deed, do not sound a trumpet
before you as the hypocrites do in the synagogues and in the
streets, that they may have glory from men. Assuredly, I say to
you, they have their reward.
