Matthew 6:3-5

3But thou, when thou doest alms, let not thy left hand know what thy right hand does;

4so that thine alms may be in secret, and thy Father who sees in secret will render [it] to thee.

5And when thou prayest, thou shalt not be as the hypocrites; for they love to pray standing in the synagogues and in the corners of the streets so that they should appear to men. Verily I say unto you, They have their reward.
