Matthew 6:3-5

3But when thou doest alms, let not thy left hand know what thy right hand doeth: 4That thy alms may be in secret: and thy Father who seeth in secret himself shall reward thee openly.

5And when thou prayest, thou shalt not be as the hypocrites are : for they love to pray standing in the synagogues and in the corners of the streets, that they may be seen by men. Verily I say to you, They have their reward.
