Do not let your left hand know what your right hand is doing
“Thus, when you give alms, sound no trumpet before you, as the hypocrites do in the synagogues and in the streets, that they may be praised by men. Truly, I say to you, they have their reward. But when you give alms, do not let your left hand know what your right hand is doing, so that your alms may be in secret; and your Father who sees in secret will reward you." Matthew 6:1-6,16-18
