1 “Beware of practicing your righteousness before other people in order to be seen by them, for then you will have no reward from your Father who is in heaven. 2 “Thus, when you give to the needy, sound no trumpet before you, as the hypocrites do in the synagogues and in the streets, that they may be praised by others. Truly, I say to you, they have received their reward. 3 But when you give to the needy, do not let your left hand know what your right hand is doing, 4 so that your giving may be in secret. And your Father who sees in secret will reward you.
Matthew 6:1-4
