Matthew 6:1-2

1 "Take heed that ye do not your almsgiving before men, to be seen by them; otherwise ye have no reward from your Father who is in Heaven.

2 Therefore when thou givest thine alms, do not sound a trumpet before thee, as the hypocrites do in the synagogues and in the streets, that they may have glory of men. Verily I say unto you, they have their reward.
