Matthew 6:1-2

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.

2Therefore, 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.
