Matthew 6:1-4, 19

“Beware of practicing your righteousness before others to be seen by them; otherwise you have no reward from your Father in heaven. So whenever you do tzadakah, do not sound a trumpet before you as the hypocrites do in the synagogues and on the streets, so that they may be glorified by men. Amen, I tell you, they have their reward in full! But when you do tzadakah, do not let your left hand know what your right hand is doing, so that your tzadakah may be in secret; and your Father, who sees in secret, shall reward you.

“Do not store up for yourselves treasures on earth, where moth and rust destroy and where thieves break in and steal.
