Matthew 6:3-5

3But when you give to the needy, do not let your left hand know what your right hand is doing, 4so that your giving may be in secret. And your Father, who sees what is done in secret, will reward you.

5And when you pray, do not be like the hypocrites. For they love to pray standing in the synagogues and on the street corners to be seen by men. Truly I tell you, they already have their full reward.
