Matthew 6:3-5

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

4that your charitable deed may be in secret; and your Father who sees in secret will Himself reward you openly.

5“And when you pray, you shall not be like the hypocrites. For they love to pray standing in the synagogues and on the corners of the streets, that they may be seen by men. Assuredly, I say to you, they have their reward.
