Matthew 6:17-21

But when you fast, comb your hair and wash your face. Then no one will notice that you are fasting, except your Father, who knows what you do in private. And your Father, who sees everything, will reward you. “Don’t store up treasures here on earth, where moths eat them and rust destroys them, and where thieves break in and steal. Store your treasures in heaven, where moths and rust cannot destroy, and thieves do not break in and steal. Wherever your treasure is, there the desires of your heart will also be.
