References for Matthew 6:1
So whenever you give to the poor, don't sound a trumpet before you, as the hypocrites do in the synagogues and on the streets, to be applauded by people. I assure you: They've got their reward!
But when you give to the poor, don't let your left hand know what your right hand is doing,
so that your giving may be in secret. And your Father who sees in secret will reward you.
