Matthew 6:3-5

3But when you do tzadakah, do not let your left hand know what your right hand is doing,

4so that your tzadakah may be in secret; and your Father, who sees in secret, shall reward you.

5“When you pray, do not be like the hypocrites; for they love to pray standing in the synagogues and on the street corners, so that they may be seen by others. Amen, I tell you, they have their reward in full!
